What are some good prog rock bands/albums?

Jethro Tull - Aqualung + Thick as a Brick

Mix of early heavy metal with English folk and classical- awesome!

Pink Floyd- Dark Side of the Moon, Wish You Were Here, Meddle

Not so much complex as very sonically adventurous

King Crimson- In the Court of the Crimson King, Red

First album is dark creepy medieval-sounding stuff, the second

Traffic- John Barleycorn Must Die

Folk and jazz influenced

Yes- start with Fragile

Other bands with progressive tendencies might include 80s Metallica (Master of Puppets, etc.), Iron Maiden (Powerslave, etc.), and Tool (Lateralus is a great album, as the other guy mentioned). Dream Theater is progressive metal although I've never been much into them.

I think that Pink Floyd is a great prog rock band

Some of there best albums:

Dark Side of the Moon

Wish You Were Here

The Wall

piper at the gates of dawn

I also consider Rush

Tool is a little overrated, but their Album Lateralus isn't. It is absolutely brilliant. Start there.

Frances the Mute by the Mars Volta is unbelievable, if a little inaccessible at first.

Also, you probably already know about them but Pink Floyd is good prog rock.

EDIT: Also Dream Theater are said to be technically the best band in existence. Personally I don't listen to them but man they can play...

Rush is the best Prog rock band. Their best albums are moving pictures, 2112, fly by night

For some of the originals, maybe try :~

Mike Oldfield ~ "Tubular Bells" (1973)

Mike Oldfield ~ "Ommadawn"

Pink Floyd ~ "The Dark Side of the Moon"

Pink Floyd ~ "Wish You Were Here"

Focus ~ "Hocus Pocus : The Best of Focus"

Jethro Tull ~ "Aqualung"

Rush and Yes are pretty good. they're classic, but they rock!edit:

Pink Floyd is also really good. you should check out their Dark Side of the Moon album.

I agree with rush, they're a great progressive rock band.

Albums: 2112, and Moving pictures. both by rush.

If you've heard the song Tom Sawyer that's Rush.
