Maybe the most unknown Greek band playing hard rock psychedelia in the seventies was a group with an extremely puzzling name: Τα 4 Επίπεδα Της Ύπαρξης (or The Four Levels Of Existence to all you non-Greeks out there). They made one LP in 1976, on a very small label (called Venus) and in a very limited edition. The album almost immediately disappeared and was never released again. Surprisingly, the sound is somewhat akin to that of Spacemen Three!
