You might be curious as to why my username is what it is. Well, here is the "not-so-related-to-me" story:
Syd Barrett was a founding member of Pink Floyd before they got famous (Pre-The Dark Side Of The Moon/The Wall times). He wrote nearly all the songs on their first album, The Piper At The Gates Of Dawn. Today, his music isn't as popular as Pink Floyd's later material. Syd Barrett used alot of acid (especially L.S.D.) in his songwriting. The music is very "out there", so to speak.
Pink Floyd kicked him out of the band in 1968. His mental health was getting worse and worse. He was become difficult to work with. He became catatonic (he would often stare into space for very long periods of times. Even during concerts).
He had a short solo career. His first solo album was called The Madcap Laughs. This is where I got my username.
I will leave you with this video of Syd Barrett with Pink Floyd (There is more music in the video after a couple minutes):
