Although Greek progressive rock bands are perhaps not as well known as some of their northern European counterparts, Aphrodite’s Child enjoyed a successful, albeit brief, stint as Greece’s foremost prog rock group in the late 1960s. Roussos (bass/vocals), along with Vangelis (keys), Lucas Sideras (drums), and “Silver” Koulouris (guitars), produced one of the finest early progressive rock albums: 666, an album based upon the Book of Revelation.

Roussos, who enjoyed a successful solo career after the end of Aphrodite’s Child, was 68 years old.
