VAST stands for Vi­su­al Au­dio Sen­so­ry The­ater, and is the brain­child of Los An­ge­les, Cal­i­for­nia-​based singer-​song­writ­er and mu­si­cian Jon Cros­by. The 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.
