Anthony Edwin Phillips is an English musician, songwriter, and composer who co-founded the progressive rock band Genesis. He served as the group's original lead guitarist from 1967 until his departure in 1970, performing on their formative studio albums From Genesis to Revelation (1969) and Trespass (1970). His early 12-string acoustic guitar arrangements heavily shaped the band's signature pastoral sound. Phillips voluntarily left the group on the eve of their mainstream breakthrough due to increasing stage fright and health complications. This exit has frequently led music critics to compare his trajectory to that of other early departed band members.
