After a week off, the Rocktagon is back as four-time champion Alter Bridge look to continue their winning streak against newcomers The Colourist.

Alter Bridge will release their fourth studio album, Fortress, on October 8. Lead single "Addicted to Pain" has dispatched challengers such as Panic! at the Disco, Nonpoint and 17-time Rocktagon winner Asking Alexandria. Watch Alter Bridge perform unplugged for Classic Rock Magazine here.

Orange County, Calif. indie-rockers The Colourist have been gaining a lot of attention with their single, "Little Games." The quartet signed with Republic Records and just released an EP entitled Lido last month. The Colourist will support the Naked and Famous on tour later this month.
