Mogwai are our greatest living crescendo artists; painfully deliberate sculptors of the churning, yearning, forever-burning riff. None of the tasteless end-credit emotion-tugging of Explosions in the Sky or the self-important swooning of Sigur Rós—Mogwai work widescreen magic by simply having the familiar crunch of a hard-rock band, gently peppered with a variety of understated hues. Their seventh album Hardcore Will Never Die, But You Will matches a few of their classic skyscrapers with some of the melody-based indie-crunch of 2003’s college radio staple Happy Songs for Happy People—all gently colored by a newish palette of Jesu-style feedback whines, Badalamenti melancholy, and searing vocoder wail. Tonight, they team with fellow Scottish art-rockers Errors, who mix a taut ’80s dance-punk energy with the burnt-end noise of modern art-loft punk-scuzz.
