All nominees are winners.
Chicago Transit Authority is a bass demo LP . The percussion breaks in "Beginnings" and "I'm a Man" will also show off a good system.
D&D Layla wins for awful sound quality. Thankfully, the music makes up for it.
My vote for Prog- Yes" Tales from Topographic Oceans "
Not REALLY a double album, but the 1st 2 Pink Floyd albums were re released as a double set-"The Piper at gates dawn" & "Saucer full of secrets" in 1973. It's the only realistic way to find those 2 albums unmolested at a reasonable price. Decent SQ too.
This has to be the most "Punk" song ever written before "Punk"?
Quadrophenia is my fave Who album.
