Bands Where You Have To Specify You Only Like "The Old Stuff"
I always have to do this just to make sure I'm not misrepresenting myself.
Pink Floyd -- I don't like "Pipers...." or their last three.. Meddle to The Final Cut
Supertramp - again, just the Roger stuff, but another band who's first couple albums weren't as great as their next few.
The Who - like Led Zeppelin, their last couple albums (classic lineup) weren't great as the previous ones, but I think they died with Keith.
The Rolling Stones - last album I liked was "Tattoo You" and the best songs were almost a decade old.
Black Sabbath - I only like the Ozzy years
David Bowie - one of a couple of artists who actually had a handful of good songs in the last 30-40 years, but its nothing compared to his 70s work
