Pink Floyd - Wish Your Were Here (1975)

I'm probably in the minority, but I believe 'Dark Side of the Moon' is a bit overrated. It never made much of an impression on me the first time I heard it in the '70s (listening to the album, I often ended up scratching my head trying to figure out why it was so rabidly hyped!), and it doesn't impress me now.

I'll take 'Wish You Were Here' over it anytime, though my main reason for liking this space-rock showcase is Richard Wright's stratospheric synth solo on 'Welcome to the Machine'.
