vast

adj. large, enormous, huge

VAST stands for Visual Audio Sensory Theater, and is the brainchild of Los Angeles, California-based singer-songwriter and musician Jon Crosby.The musical outfit began when Jon Crosby was sixteen, and at the time the other members of the group consisted of a drum machine and a bass player. VAST's concerts included elements of performance art as well as music, employing display monitors and other visual effects onstage.The band first had some success when a local radio station gave one of their demo tapes  consistent air-time. Crosby sent demo tapes to several New York City recording companies, eventually signing with Elektra Records. Thomas Garadis, Steve Clark, and Rowan Robertson made up the hastily-assembled band along with Crosby. After touring America and releasing their first album, named simply Visual Audio Sensory Theater (1998), they began work on a second album, entitled Music For People (2000). Before it was finished, Robertson left in pursuit of a solo career. After auditioning, Justin Cotta was chosen to replace him. The new quartet began another US tour. In 2001, Cotta and Clark decided to leave the band to form their own band.
