Larry Grenadier (born February 6, 1966 in San Francisco) is an American jazz double bassist. 　　Grenadier's father, Albert, was a trumpet player, and his two brothers, Phil and Steve, play trumpet and guitar, respectively. Grenadier began on trumpet when he was 10 years old before beginning to play the bass the following year. Grenadier's father helped introduce him to the instruments and music theory. Larry's older brother Phil began listening to jazz around this time, influencing his sibling's musical interests. Grenadier began listening to several jazz bassists including John Patitucci, Ray Brown, Charles Mingus, Brian Bromberg, Les Claypool, Richard Davis, Jeff Chambers, Wilbur Ware and Oscar Pettiford, among others. 　　At age 12 Grenadier began formal study of the acoustic bass, learning from local jazz bass players Chris Poehlor, Paul Breslin, and Frank Tusa and later classical bassists Michael Burr and Steven Tromontozzi. At 16, Grenadier had a busy career playing in the San Francisco Bay Area with both local musicians and those traveling through town in need of a bass player. Some of these musicians included Harvey Wainapel, Bobby Hutcherson, Joe Henderson, Larry Vuckovitch, Eddie Henderson, Bruce Forman, Eddie Marshall, Vince Lateano, George Cables and Donald Bailey, Toots Thielmans, Johnny Griffin, Charles McPherson, Anita O'Day, and Frank Morgan, among others. 　　Grenadier studied at Stanford University and graduated in 1989 with a bachelor's degree in English Literature. At Stanford, he met Stan Getz, with whom he toured.
