Jon Crosby (born July 25, 1976) is an American musician, founder of the musical outfit VAST.
At the age of 13, he was profiled in Guitar Player magazine and Shrapnel Magazine as a rising young star. He developed a love for classical music after watching the film Amadeus. When he met a girl named Michelle in 6th Grade, he learned to play The Beatles' hit "Michelle" on guitar to impress her. This sparked his interest in The Beatles, and in rock music in general. Crosby's other influences include Steve Vai, Joe Satriani, U2, and Depeche Mode. He formed VAST in 1993, at the age of 16, after moving to Petaluma, CA with friends Mike Alioti and Dimitri Katzoff, formerly of ska-band The Conspiracy, though that line-up was short-lived and would be frequently supplanted. He played few early shows, mainly at the famed Phoenix Theater, where many early acts—like Green Day -- got their first big break.
At 19, Crosby's manager/ex-girlfriend Sakina Sati took him to New York, along with ex-members Daniel Alva and Stephen Garver, for the purpose of shopping his demo tapes through Shiva Baum, former manager for Opiate for the Masses, and a bidding war broke out; he then signed with Elektra. Two albums were released by Elektra - Visual Audio Sensory Theater in 1998 and Music For People in 2000. In 2002, however, Crosby left the label. 2003 saw him break new ground when he released two digital download albums, Turquoise 3.x and Crimson 3.x. He then moved on to Carson Daly's 456 Entertainment, where Nude was released in 2004.
