The next Nile album, another Seventh Void album, another A Pale Horse Named Death album, another Fear Factory album, Buckethead's next 14 albums...
It would be great if Baroness released another album.
I'd like to hear another Metallica album that's actually a Metallica album.
Maybe the new Black Sabbath album will be out in '12?
Definitely gotta see them on tour.
I've also read that there's another Alice in Chains album in the works as well as another Tool album.
Some other mentions: Drudkh, a live album from Death, an Oomph! album, Cannibal Corpse, Ministry, Slayer, Ahab, Down (hopefully better than their last album), Kreator, Nine Inch Nails (hope they tour), Dreaming Dead.
I also heard that Type O Negative has resurrected the zombie of Peter Steele and are going to start working on another album after they figure out a way to keep his d*ck from falling off.
Not really... Sure wish those guys were still around, though.
More than any other band.
