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.

The Kid,

Are you saying those are good albums? I sure think so. You may have good taste;)
Of course the first Stone Roses album is a classic and widely accepted as such,in the Music For The Millenium poll conducted in 1999-a survey of critics and public had the album in the top 5,some 10 years after it's release.
This is actually a great question,it's got me racking my brains which shouldn't take long.
Of course I think we can all think of songs or groups of songs we heard live by famous bands that when we heard the official recorded versions seemed lacking,likewise albums or arrangements of great songs that failed to deliver their potential when recorded but all the artists I can think of who did this (Dylan is infamous for not delivering in the studio and leaving great songs off of albums),did release great albums at earlier stages in their career.....................good question
