Crazy Diamond is a 1993 triple-CD boxed set of Syd Barrett's two 1970 albums The Madcap Laughs and Barrett, and Opel, an out-takes compilation from 1988. All discs are further augmented by various alternate takes. "Our main plan was to find Syd's acoustic takes, before the other musicians were drafted in to overdub them. But we stumbled across some fascinating material that sheds new light on Syd's working methods." — Phil Smee
