Like a supernova, Roger "Syd" Barrett burned briefly and brightly, leaving an indelible mark upon psychedelic and progressive rock as the founder and original singer, songwriter, and lead guitarist of Pink Floyd. In early 1968 Syd left and/or was fired from the band, after his erratic behaviour had made him too difficult to deal with. After a period of hibernation, Barrett re-emerged in 1970 with a pair of albums, The Madcap Laughs and Barrett, which featured considerable support from his former bandmates (especially his replacement, David Gilmour, who produced most of the sessions). Members of Soft Machine also play on these records, which have a ragged, unfinished, and folky feel.
