More than 20 years into their career, the silhouette of symphonic post-rockers Godspeed You! Black Emperor remains as unmistakable as ever: tentative wisps of sound that build to heights of almost agonizing glory. Following the thread of 2012’s relatively optimistic Allelujah! Don’t Bend! Ascend!, Luciferian Towers is a volcanic, inspiring album with hints of Near Eastern music (“Undoing a Luciferian Towers”), Irish wake ballads (“Bosses Hang, Pt. I”), and psychedelia beamed in from an imaginary Western (“Anthem for No State, Pt. III”)—a cross-cultural portrait of music as an expression of hope and resistance.
