Bands with great second albums


Bands that had a great second album. We all know the obvious ones Led Zeppelin, Hendrix, The Beatles. What are your votes for great second albums. Some of mine are:
Neil Young - Everybody Knows This Is Nowhere
Elvis Costello - This Years Model
Allman Brothers Band - 'Idlewild South'
Badfinger - No Dice

Tough to put out a better second album than Radiohead's "The Bends".  Perhaps Nirvana's "Nevermind" is the right there with it.  In the jazz world I often prefer a bandleader's second album such as Ornette Coleman's "Change of the Century".  You can see these guys' confidence building after a successful debut is under their belt and they real start pushing it, in a good way.
