My least favourite though still not that bad an album. The other two are both on the same level. I think part of the reason I like this one least is that it's really over produced and so some songs lack the energy they should have. The debut is just damn awesome rock and Revelations is just so original for a band of these days and just so funky. Cornell also sounds his worst with AS on this album.
It took a while but it grew on me. Not a bad album, its just different. Audioslave I think gets a bad rap mostly because they aren't Rage Against The Machine anymore and that's hardly fair. Out of Exile wasn't their best work, but its not terrible at all, give it some time.
