Fortress is the product of a protracted creative process that saw the band - singer Ken Block, guitarists Andrew Copeland and Ryan Newell, bassist Jeff Beres and drummer Mark Trojanowski - working at various times and in different combinations with producers Mike Clink, Richie Zito and Paul Ebersold (who produced Somewhere More Familiar), exercising extra care in crafting the album for maximum effectiveness.
As Block recently admitted to The Gainesville Sun, "We wanted somebody that had made some big-sounding records to capture the energy that our indie records didn't have. We were hungry to make a real record."
All of the participants seem to agree that the extra effort was worth the trouble. "I've seen a lot of bands go in and try and get their live sound on a disc, and it didn't happen," says Copeland. "We got lucky this time and were able to capture that."
Indeed, several of Fortress's tracks introduce new stylistic elements to the bluesy, melodic folk-rock sound the band established on its debut. "Change Your Mind" and "Surreal" mix slashing, metallic riffs and subtle melodies, while "Beautiful Thing" introduces an airily acoustic approach. The waltz-time "Champagne High" (with guest vocals by Indigo Girl Emily Saliers) underscores its prettiness with an unmistakable lyrical sting, and the epic yet introspective title track reflects on the darker side of the band's experiences with fame and success.
As Copeland told The Album Network, "We've matured as musicians and songwriters... It's a new and improved Sister Hazel."
