I'm not into alt rock, but I do have some stuff from hard rock groups considered by some to be alternative. I don't consider any of these alternative.
-The Cult (I do, however, consider the 1994 s/t to be alt, and the first two were alt in their time...I suppose)
-Beautiful Creatures
-Buckcherry
-Jet
-Nashville P*ssy
-The Trews
-U2
