The Monterey International Pop Music Festival was a three-day concert event held June 16 to June 18, 1967 at the Monterey County Fairgrounds in Monterey, California.

Crowd estimates for the festival have ranged from 25,000-90,000 people, who congregated in and around the festival grounds. The fairgrounds’ enclosed performance arena, where the music took place, had an approved festival capacity of 7,000, but it was estimated that 8,500 jammed into it for Saturday night’s show.

Festival-goers who wanted to see the musical performances were required to have either an 'all-festival' ticket or a separate ticket for each of the five scheduled concert events they wanted to attend in the arena: Friday night, Saturday afternoon and night, and Sunday afternoon and night. Ticket prices varied by seating area, and ranged from $3 to $6.50.

The festival is remembered for the first major American appearances by The Jimi Hendrix Experience, The Who and Ravi Shankar, the first large-scale public performance of Janis Joplin and the introduction of Otis Redding to a large, predominantly white audience.

The festival was planned in seven weeks by promoter Lou Adler, John Phillips of The Mamas & the Papas, producer Alan Pariser and publicist Derek Taylor. The Monterey location had been known as the site for the long-running Monterey Jazz Festival and Monterey Folk Festival; the promoters saw the Monterey Pop festival as a way to validate rock music as an art form in the way in which jazz and folk were regarded. The organizers succeeded beyond all expectations.

The artists performed for free with all revenue donated to charity, except for Ravi Shankar, who was paid $3,000 for his afternoon-long performance on the sitar. Country Joe and the Fish were paid $5,000 not by the festival itself, but from revenue generated from the D.A. Pennebaker documentary.

Lou Adler later reflected:

…Our idea for Monterey was to provide the best of everything -- sound equipment, sleeping and eating accommodations, transportation -- services that had never been provided for the artist before Monterey.

We set up an on-site first aid clinic, because we knew there would be a need for medical supervision and that we would encounter drug-related problems. We didn't want people who got themselves into trouble and needed medical attention to go untreated. Nor did we want their problems to ruin or in any way disturb other people or disrupt the music.

Our security worked with the Monterey police. The local law enforcement authorities never expected to like the people they came in contact with as much as they did. They never expected the spirit of 'Music, Love and Flowers' to take over to the point where they'd allow themselves to be festooned with flowers.

With two huge singles behind them, the Airplane was one of the major attractions of the festival.

The Who

Although already a big act in the UK, and now gaining some attention in the US after playing some New York dates two months earlier, The Who were propelled into the American mainstream at Monterey. The band used rented Vox amps for their set, which were not as powerful as their regular Sound City amps which they had left in England to save shipping costs. At the end of their frenetic performance of "My Generation", the audience was stunned as guitarist Pete Townshend smashed his guitar, smoke bombs exploded behind the amps and frightened concert staff rushed onstage to retrieve expensive microphones. At the end of the mayhem, drummer Keith Moon kicked over his drum kit as the band exited the stage. The Who, after winning a coin toss, performed before Jimi Hendrix, as Townshend and Hendrix each refused to go on after the other, both having planned instrument-demolishing conclusions to their respective sets.

The Jimi Hendrix Experience

Hendrix ended his Monterey performance with an unpredictable version of "Wild Thing", which he capped by kneeling over his guitar, pouring lighter fluid over it, setting it on fire, and then smashing it in to the stage seven times before throwing its remains into the audience. This produced wild, unpredictable sounds, and these actions contributed to his rising popularity in the United States. Robert Christgau later wrote in The Village Voice of Hendrix's performance:

“ Music was a given for a Hendrix stuck with topping the Who's guitar-smashing tour de force. It's great sport to watch this outrageous scene-stealer wiggle his tongue, pick with his teeth, and set his axe on fire, but the showboating does distract from the history made that night—the dawning of an instrumental technique so effortlessly fecund and febrile that rock has yet to equal it, though hundreds of metal bands have gotten rich trying. Admittedly, nowhere else will you witness a Hendrix still uncertain of his divinity.”

Janis Joplin

Monterey Pop was also one of the earliest major public performances for Janis Joplin, who appeared as a member of Big Brother and The Holding Company. Joplin gave a provocative rendition of the song "Ball 'n' Chain". Columbia Records signed Big Brother and The Holding Company on the basis of their performance at Monterey.

Otis Redding

Ravi Shankar

Ravi Shankar was another artist who was introduced to America at the Monterey festival. The Raga Dhun (Dadra and Fast Teental) (which was later miscredited as "Raga Bhimpalasi"), an excerpt from Shankar's four-hour performance at the 1967 Monterey Pop Festival, concluded the Monterey Pop film, introducing the artist to a new generation of music fans.

The Mamas & the Papas

The Mamas & the Papas performed the closing act of the festival, as member John Phillips helped organize the festival. They also introduced several of the acts, including Scott McKenzie. They played some of their biggest hits, including "Monday, Monday" and "California Dreamin".

Cancellations and no-shows

Several acts were also notable for their non-appearance.

The Beach Boys, who had been involved in the conception of the event and were at one point scheduled to headline and close the show, failed to perform. This resulted from a number of issues plaguing the group. Carl Wilson was in a feud with officials for his refusal to be drafted into military service during the Vietnam War. The group's new, radical album Smile had recently been aborted, with band leader Brian Wilson in a depressed state and unwilling to perform (he hadn't performed live with the group since late 1964, although he would do so in Honolulu, Hawaii in August 1967). Since Smile had not been released, the group felt their older material would not go over well. The cancellation permanently damaged their reputation and popularity in the US, which would contribute to their replacement album Smiley Smile charting lower than any other of their previous album releases.

The Beatles were rumored to appear because of the involvement of their press officer Derek Taylor, but they declined, since their music had become too complex to be performed live. Instead, at the instigation of Paul McCartney, the festival booked The Who and the Jimi Hendrix Experience.

The Kinks were invited but could not get a work visa to enter the US because of a dispute with the American Federation of Musicians.

Donovan was refused a visa to enter the United States because of a 1966 drug bust.

Captain Beefheart & the Magic Band was also invited to appear but, according to the liner notes for the CD reissue of their album Safe As Milk, the band turned the offer down at the insistence of guitarist Ry Cooder, who felt the group was not ready.

Dionne Warwick and The Impressions were advertised on some of the early posters for the event, but Warwick dropped out because of a conflict in booking that weekend. She was booked at the Fairmont Hotel; the hotel was reluctant to release her and it was thought that cancelling that appearance would negatively affect her career.

Even though the logo for the band Kaleidoscope is seen in the film as a pink sign just below the stage, the band did not perform at the Monterey Festival.

Although The Rolling Stones did not play, guitarist and founder Brian Jones attended and appeared on stage to introduce Hendrix. The group was on the short list of invitees, but was unable to get work visas because of the drug arrests of Mick Jagger and Keith Richards.

It was long rumored that Love had declined an invitation to Woodstock, but Mojo Magazine later confirmed that it was the Monterey Festival they had rejected.

The promoters also invited several Motown artists to perform and even were going to give the label's artists their own slot. However, Berry Gordy refused to let any of his acts appear, even though Smokey Robinson was on the board of directors.

The Doors did not appear because the coordinators forgot to invite them. Drummer John Densmore, in his book Riders on the Storm, expressed his belief that the band was not invited because its music didn't express the "peace and love" ideals of the time. The real matter instead was that, back in 1965, they took their demo to the Dunhill Records, where Lou Adler, the head man, rejected the whole thing. "Nothing here I can use" he said, "That's ok, man. We don't want to be used anyway" Morrison replied. Because Lou Adler was also one of the promoters of the Monterey Pop Festival, The Doors were never invited to play there.

The Monkees were the biggest-selling musical act in the United States in 1967 and were seriously considered to play, but after weeks of deliberation, John Phillips and Lou Adler decided not to invite them. However, group members Micky Dolenz (in full American Indian buckskins and headdress) and Peter Tork attended the festival and mingled with musicians backstage. Tork was asked to introduce Buffalo Springfield, his favorite group, for their set. Tork also introduced Lou Rawls and was involved in a bizarre incident where he walked out onstage in the middle of the Grateful Dead's set when he went out to try to stop fans from climbing on stage and dancing as well as to inform the crowd that The Beatles were not at the festival in disguise.

Music writer Rusty DeSoto argues that pop music history tends to downplay the importance of Monterey in favor of the "bigger, higher-profile, more decadent" Woodstock Festival, held two years later. But, as he notes:

…Monterey Pop was a seminal event... featuring debut performances of bands that would shape the history of rock and affect popular culture from that day forward. The County Fairgrounds in Monterey, California … had been home to folk, jazz and blues festivals for many years. But the weekend of June 16–18, 1967 was the first time it was used to showcase rock music.

The festival launched the careers of many who played there, making some of them into stars virtually overnight, including Janis Joplin, Laura Nyro, Canned Heat, Otis Redding, Steve Miller and Indian sitar maestro Ravi Shankar.

Monterey was also the first high-profile event to mix acts from major regional music centers in the U.S.A. — San Francisco, Los Angeles, Chicago, Memphis and New York City — and it was the first time many of these bands had met each other in person. It was a particularly important meeting place for bands from the Bay Area and L.A., who had tended to regard each other with a degree of suspicion — Frank Zappa for one made no secret of his low regard for some of the San Francisco bands — and until that point the two scenes had been developing separately along fairly distinct lines. Paul Kantner of Jefferson Airplane said “The idea that San Francisco was heralding was a bit of freedom from oppression.”

Monterey also marked a significant changing of the guard in British music. The Who and Eric Burdon and The Animals represented the UK, with the Beatles and the Rolling Stones conspicuously absent. The Stones' Brian Jones wafted through the crowd, resplendent in full psychedelic regalia, and appeared on stage briefly to introduce Jimi Hendrix. It would be two more years before The Stones hit the road, by which time Jones was dead, and the Beatles never toured again. Meanwhile, The Who leapt into the breach and became the top British touring act of the period.

Also notable was the festival's innovative sound system, designed and built by audio engineer Abe Jacob, who started his career doing live sound for San Francisco bands and went on to become a leading sound designer for the American theater. Jacob's groundbreaking Monterey sound system was the progenitor of all the large-scale PAs that followed. It was a key factor in the festival's success and it was greatly appreciated by the artists—in the Monterey film, David Crosby can clearly be seen saying "Great sound system!" to band-mate Chris Hillman at the start of the Byrds' soundcheck. Lighting by Chip Monck attracted the attention of the Woodstock Festival promoters.

Electronic music pioneers Paul Beaver and Bernie Krause set up a booth at Monterey to demonstrate the new electronic music synthesizer developed by Robert Moog. Beaver and Krause had bought one of Moog's first synthesizers in 1966 and had spent a fruitless year trying to get someone in Hollywood interested in using it. Through their demonstration booth at Monterey, they gained the interest of acts including The Doors, The Byrds, The Rolling Stones, Simon & Garfunkel and others. This quickly built into a steady stream of business, and the eccentric Beaver was soon one of the busiest session men in L.A. He and Krause earned a contract with Warner Brothers.

The festival was the subject of an acclaimed documentary movie entitled Monterey Pop, by noted documentary filmmaker D.A. Pennebaker. Pennebaker's team used recently developed portable 16mm crystal-sync motion picture cameras that stayed synchronized with double-system sound-recording systems.

The film stock was Eastman Kodak's recently released "high-speed" 16mm Ektachrome 100 ASA color reversal motion picture stock, without which the nighttime shows would have been virtually impossible to shoot in color. Sound was captured by Wally Heider's mobile studio on state-of-the art eight-track tape, with one track used for the crystal-sync tone, to synchronize it with the film cameras.

The Grateful Dead believed that the film was too commercial and refused permission to be shown. The screening of the film in theaters nationwide helped raise the festival to mythic status, rapidly swelled the ranks of would-be festival-goers looking for the next festival, and inspired new entrepreneurs to stage more such festivals around the country.

An expanded version of the documentary has been released on DVD by the Criterion Collection.

The audio recordings of the festival eventually became the basis for many albums, most notably the 1970 release Historic Performances Recorded at the Monterey International Pop Festival featuring partial sets by Otis Redding and Jimi Hendrix.

Other releases recorded at the festival included the Grateful Dead, Jefferson Airplane and Ravi Shankar. In 1992, a four-CD box set was released featuring performances by most of the artists; various other compilations have been released over the years.
