Lindsay Cooper—who was British bassoon/oboe player for Henry Cow, Comus, David Thomas and the Pedestrians, and many other avant-garde/progressive groups—passed away Sept. 18. She was a co-founder of the Feminist Improvising Group and also recorded several solo albums, including 1980's Rags. She also contributed to several important prog records, including Egg's The Civil Surface, Mike Oldfield's Hergest Ridge, Hatfield and the North's The Rotters' Club, and Steve Hillage's Fish Rising.

Cooper had suffered from multiple sclerosis since the late ’70s and had not been active in music since the late '90s. RIP, Lindsay Cooper.
