Sinclair managed the
proto-punk band
MC5 from 1966 through 1969. Under his guidance the band embraced the counter-culture revolutionary politics of the
White Panther Party, founded in answer to the
Black Panthers' call for white people to support their movement. The album
Kick Out the Jams caused some controversy due to John Sinclair's inflammatory
liner notes and the title track's rallying cry of "Kick out the jams,
motherfuckers!" According to
Wayne Kramer the band recorded this as "Kick out the jams, brothers and sisters!" for the single released for radio play;
Rob Tyner claimed this was done without group consensus. The edited version also appeared in some LP copies, which also withdrew Sinclair's excitable comments. The album was released in January 1969; reviews were mixed, but the album was relatively successful, quickly selling over 100,000 copies and peaking at #30 on the
Billboard 200 chart in May 1969 during a 23-week stay. During this period, Sinclair booked "The Five" as the regular house band at Detroit's famed
Grande Ballroom in what came to be known as the
"Kick out the Jams" shows. He was managing the MC5 at the time of their free concert outside the 1968
Democratic National Convention in Chicago. The band was the only group to perform before police broke up the massive
anti-Vietnam war rally. Eventually, the MC5 came to find Sinclair's politics too heavy-handed. He and the band separated in 1969. In 2006, Sinclair joined MC5 bassist
Michael Davis to launch the Music Is Revolution Foundation, serving as a general board member. They issued a CD,
Music is Revolution: From the John & Leni Sinclair library with Leni Sinclair. Oak Park, MI: Book Beat Gallery, 2000, a spoken word CD (compiled from 50 hours of historical recordings at the
Bentley Historical Library, plus an illustrated book featuring posters and pictures of the MC5, an documenting radical political history. The band and Sinclair lived together in a commune on Hill Street in Ann Arbor for several years. Marijuana and hallucogenics were commonly used. He was said to be charismatic and theatrical. As the
Detroit Free Press wrote: "Gleefully proclaiming the joys of rock 'n' roll, drugs and sex in the streets, John Sinclair reigned as a nationally celebrated troubadour of youth rebellion during the psychedelic era, playing a lead role in making Detroit and Ann Arbor counterculture hot spots with the MC5 band, the White Panther Party, cutting-edge concerts and flamboyant rhetoric." He proselytized a "utopian dream of a post-industrial society based on leisure and marijuana never went beyond a small group of collaborators.-" seeing to "to mount a "total assault" on the "death culture" of America." He proclaimed the "pig-death machine" to be "anti-life by definition." Sinclair was unapologetic, although he later acknowledged his hippie driven utopia was a "naïve fantasy." While managing the MC5 and leading the White Panthers he was able to build the Detroit's
Grande Ballroom into a Midwestern concert venue. He was an influence of
Iggy Pop's career. Iggy Pop started as the flamboyant lead singer of the
Psychedelic Stooges. Meanwhile, Sinclair spread his rebellious gospel, making appearances at high schools and other venues. In
Guitar World Sinclair proclaimed that it was "the crazed guerilla warfare we were waging with the MC5." His death came only two months after MC5 co-founder
Wayne Kramer's death. ==Imprisonment and public support==
