Best band never to release a truly great album?


Yeah, I know, another poll, but these are kind of fun and this one may be a little different. Let's limit it to no earlier than the late 60's (when the album began to be more important than the single). What musician/band do you really like, but has never quite put it all together to make that brilliant album you know is in them.

I'll start by nominating Jethro Tull. Lot's of great songs, but I cannot think of a single Tull record I would call an unqualified success.

I certainly have to agree with Bomarc's pick of the Yardbirds. How could that much talent never produce a truley killer album???? First you've got Clapton, then later Jeff Beck, and finally Jimmy Page, along with Keith Relf throughout. Every album has it's gems, but not one solid from beginning to end. Don't get me wrong, I have all of their albums, but there is no Revolver in the bunch. Zaikesman had a great call with Pretty Things, but I think Parachute and S.F. Sorrow are great albums start to finish. They were just overshadowed by The Beatles. Jond nailed the Dead with three great studio albums. BBA was a good call, but they did release the double Live in Japan lp which is good start to finish. Roy B? I love all his stuff. I really can't think of a better pick than the Yardbirds. Tom
"Roger the Engineer" might make the greatness cut, although I think the band's best work came earlier, in the first year with Beck and those great singles that made up Side 1 of the U.S. album "Having a Rave Up." Fill that period out ("Shapes of Things") rather than the random picks from "Five Live Yardbirds," and you would have a truly great Yardbirds album.

As for the Dead, it should be obvious that I am not among the "committed," but I'll take your word for it, Jond.
Trey, I'm afraid you're gonna have to make your case why, if you don't consider Now!, Out of Our Heads, December's Children, Beggar's Banquet, Let it Bleed, or Sticky Fingers (and possibly even 12 X 5, Aftermath, Exile on Main Street, or Some Girls) to be great albums.
Curbach , this is a great thread, but I have to disagree with the Tull comment. Songs from the wood is a very good record and Crest of a Knave is great. Trey, I have to agree with Zman, the stones have several great albums, Beggar's Banquet is an excellent album.
