On Tuesday, a spokeswoman for Pink Floyd said that Syd Barrett, co-founder of one of the most influential bands of all time died at the age of 60.

While the cause of death wasn’t commented on, the death did occur several days ago. Though Barrett chose to remain in hiding over the last several years, it’s a well-known fact that he suffered from diabetes for many years.

Throughout his life, Barrett (born Roger Keith Barret) wrote several of Pink Floyd’s songs and actually launched the band in 1965. A brilliant guitarist of his time, his prominent LSD use proved to be his downfall and he split from the band in 1968.

While he did release two solo albums afterwards (The Madcap Laughs and Barrett) he eventually retired from the music business entirely.
