I like Vangelis' blend of electronic and symphonic music. This album features vocals from Jon Anderson on one song, a real bonus to me. This might not be precisely progressive rock, but it is progressive music. It's also a diverse set of music. I should mention that I reviewed it from the original vinyl, so the division between the songs might be a bit off on my review as it's hard to tell where one ends and another begins sometimes.
