Franti began his music career in 1986 as part of the industrial punk/spoken word band The Beatnigs. While attending the University of San Francisco and living above KUSF he developed a fascination with music and decided to start a band. The Beatnigs included Dancer and percussionist Rono Tse; the band released a self-titled LP and an EP Television on Alternative Tentacles records. The records received some critical acclaim but little fame beyond the San Francisco Bay Area.
The 1988 LP release The Beatnigs was recorded at Dancin' Dog Studio in Emeryville and distributed by Alternative Tentacles. In addition to Michael Franti and Ron Tse, the band included Henry Flood on percussion, Andre Flores on keyboards, and Kevin Carnes on vocals. All of the band members made multiple instrumental contributions, including industrial percussion.
In 1994, Franti formed a new band called Spearhead with a few studio Musicians, including mainstay Carl Young, and announced the dissolution of Disposable Heroes of Hiphoprisy. Their first release, Home, in September 1994, was a departure from the politically charged rap of the Disposable Heroes and drew more from funk and soul music. The album was produced by Franti and Joe Nicolo. The song "Positive", also from the album Home, appeared on the Stolen Moments: Red Hot + Cool compilation album by the Red Hot Organization. In 1998, Spearhead recorded "I Got Plenty 'o Nuthin" with Ernest Ranglin for the Red Hot Organization's compilation album Red Hot + Rhapsody.
Their follow up album Chocolate Supa Highway was released in March 1997, with several changes in band members between releases. This album featured a return to hip hop elements and a pronounced reggae influence and included guest appearances by notables like Stephen Marley and Joan Osborne.
Franti has two sons: Ade and Cappy. He is married to emergency room nurse and jewelry designer Sara Agah. He was previously married to Tara Franti-Rye from 1998 until 2004, she is the mother of Ade.
His song "Sometimes" was included on the Soundtrack to the 1999 film, Mystery Men, as well as the Soundtrack to the 2006 film, Last Holiday. Also, under the "Spearhead" name, their cover version of The Police's 1979 No. 32 hit, "Roxanne", was featured on the Soundtrack to the 1997 film Good Burger, the full-length feature film starring Kenan Thompson & Kel Mitchell based on their characters from the popular 'Good Burger' Sketch featured on the Nickelodeon series All That.
In 2000, Franti decided not to wear any shoes, initially for three days. Since then, he has chosen to go barefoot except for occasionally wearing flip-flops as required to board an airplane or to be served in a restaurant. Franti prefers bare feet.
In 2001 Franti was awarded the Domestic Human Rights Award by Global Exchange, an international NGO based in San Francisco, for his work to end war.
Also in 2003, Franti released a mostly acoustic album, Songs from the Front Porch containing rearranged versions of older songs from Chocolate Supa Highway, Stay Human and Everyone Deserves Music as well as a couple of new tracks.
In 2006, he was invited by Australian Labour MP Jenny Macklin to show the film at Australia's Parliament House, Canberra.
Franti's music was featured twice on HBO's urban drama The Wire. "Oh My God" and "Rock The Nation", both from the album Stay Human, were used in two different episodes during the series' first season. Franti's song "Everybody Ona Move" was featured in the pilot episode of Privileged on the CW in 2008 and also in a 2009 PlayStation 3 commercial. "Yell Fire" was used to promote the FX channel series Rescue Me and was also used in the closing credits of the pilot episode of Virtuality on Fox. Showtime's Weeds featured Franti's song "Ganja Babe" in its first season, his interpretation of the Weeds theme song "Little Boxes" in Season 3, and "Say Hey" during a flash mob scene in the premiere episode of Season 5. Boston Red Sox centerfielder Shane Victorino uses the song "Light up Ya Lighter" as his batter walk-up music. "Say Hey (I Love You)" was used on the third episode of NBC's series Mercy, as well as in the opening scene of the 2010 film Valentine's Day. The same song was also used in 2010 in a commercial for Corona Light beer. The song is also featured on the Soundtrack of EA Sports game, 2010 FIFA World Cup South Africa.
Franti announced in November 2009 that he would be joining musician John Mayer on the Battle Studies Tour in spring 2010.
He appeared as himself in the 2010 music documentary Sounds Like A Revolution.
In 2012, he joined the 11th annual Independent Music Awards judging panel to assist independent musicians' careers.
