Recently, I've been getting into prog rock, and I need more bands to listen to. I dig Pink Floyd, Rush, Yes, King Crimson, and a couple others. I particularly like King Crimson's heavy, jazzy sound so bands like King Crimson are appreciated. Thanks!
Progarchives is your friend. They've basically catalogued and rated the entirety of prog so if you need more stuff to listen to the highest rated albums there.
Here's some stuff you might like though: Mahavishnu Orchestra, Can, Frank Zappa, Return To Forever
