The Piper at the Gates of Dawn
Label: Pink Floyd Records
Floyd's first is nothing like the records for which they're most known, so fasten your seatbelt if you're a beginner. Psychedelic traveler Syd Barrett's vision (jazz meets Surf Rock in a fairytale world of mice who ride bikes) is weird and fun until the creepy crawlies grab that cloud you're floating on and start eating your eyes out. This is one of the greats.
