Since it's inception over two years ago, AOS posters have negligently failed to listen to any:
Man - legendary Welsh Space Rockers - pinnacles are Greasy Truckers' Party, Be Good to Yourself at Least Once a Day and Back into the Future. Micky Jones, Most Underrated Guitarist of All Time (except for maybe Ollie Halsall) passed away last month. One of the ten best in the world according to Zappa.
Neutrons - Man spinoff
Stackridge - heretically, I rather like the late period Extravaganza album
AFT - Reading band whose only album, Automatic Fine Tuning, is a total guitar wankfest
....and the only mention Centipede get is a negative one.
Ladies (are there any?) and Gentlemen, time to pull your socks up.
