Due October 8 in North America, "Fortress" is the band's fourth studio album and first since 2010's "ABIII." The project was produced by long-time Alter Bridge producer Michael "Elvis" Baskette (Falling In Reverse, Story Of The Year, Incubus).

"When we started pre-production on this album, we pushed ourselves harder and further than we ever have previously in order to make the most out of every individual arrangement," says guitarist Mark Tremonti.
