What about phish?

Loaded is the fourth album. They also did Dark Side of the Moon once. yes they do do a lot of covers... they've covered pretty much everyone: from Miles Davis to Pavement to Frank Zappa... and so on.

I don't actually know any Phish phans, though that'll apparently change tomorrow.

That's true, Aaron. I had forgotten that Pavement was a little obsession of Trey's for a while. He was quoted in interviews a few times, seemingly very impressed with the attitude of the band. I almost bought that Dark Side of The Moon bootleg, but I don't think I'm too fond of Phish covers. Some of them are cool, but I'm positive I like the original music much better.
