Aphrodite's Child was a Greek progressive rock band formed in 1967 by Vangelis Papathanassiou, Demis Roussos, Loukas Sideras, and Silver Koulouris. They released an album entitled 666 a revelation. It was an attempt to turn the Biblical book of Revelation into a psychedelic rock experience in 1970 and the quality for nearly 50 years old is absolutely amazing.
