Commenting on Fortress, guitarist Mark Tremonti said: "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."

Tremonti continued: "We wanted this album to be our most unpredictable and exciting one yet. From the early feedback we have received, it looks like we have achieved what we set out to do."
