AC/DC "High Voltage"
Tift Merritt "Tambourine"
The Wallflowers "Breach"
The Black Crowes "The Southern Harmony & Musical Companion"


Oh yeah, Ram by Paul McCartney. Not a band of course, but that wasn't absolutely literal, right?

I may be wrong, but isn't Steely Dan's second LP COUNTDOWN....?
Many great choices here. Strange Days (already said) was the first that came to my mind. How about counting the Buckingham/Nicks era of Fleetwood Mac as a new one, and submitting Rumors, which came after their S/T LP.. (-:
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.

So many already mentioned that I would have chosen. I will add Stand Up by Jethro Tull and Candy O by The Cars.
I would add to the good suggestions above "Projections," the second album of The Blues Project. While most of my listening is to classical music, this is one of my all-time favorite rock albums.

Some great nominations, particularly The Band (big surprise ;-), Neil Young, and Procol Harum. I’ll add Bob Dylan’s The Freewheelin’, Buffalo Springfield’s Again, The Byrds’ Turn! Turn! Turn!, Juliana Raye’s Something Peculiar (great album produced by Jeff Lynne), The Traveling Wilbury’s Vol.3, Dave Edmunds’ Subtle As A Flying Mallet, Nick Lowe’s Labour Of Lust, Jellyfish’s Spilt Milk, The Dwight Twilley Band’s Twilley Don’t Mind (not as good as their incredible debut Sincerely, but that was awfully hard to match), Iris Dement’s wonderful My Life, Los Lobos’ How Will The Wolf Survive? (second English-language album), Jackson Browne’s For Everyman, David Lindley’s Win This Record!, The Sons Of Champlin’s (about the only real good Hippie band) The Sons, The Yardbirds’ Having A Rave Up With (ignoring the semi-released live album---as a debut?!), Buddy Miller’s Poison Love, plenty of others.
