Alter Bridge have hit the heights with this one. Heavier and more powerful than previous releases this is their 'metal' album. Full of amazing riffs, soaring solos and the usual great vocals from Myles Kennedy this album kicks! There's a few surprises such as Mark Tremonti taking lead vocals on Waters Rising and Myles falsetto vocals on the intro to Calm the Fire and the occasional guitar duel between the pair especially on the epic title track 'Fortress'. With Scott Philip's amazing power drumming and Brian Marshall at his best on bass this band is right up there with the best. If you've been with them from the beginning you will see how they've changed over the years. This album is definitely the hardest yet but it soars in all the right places. Awesome!!!!
