Arbor Labor Union’s debut is a loose marriage of feverish psychedelia, '70s riffs, and indie-rock ruggedness. Recalling a history of stone-faced dudes from Neil Young to Dinosaur Jr. and Pearl Jam, I Hear You is an unshaven, hair-down affair whose songs seem to gain momentum as they go—from the jammy incantations of “Mr. Birdsong” to the sun-scorched “Radiant Mountain Road” and the sludgy yet triumphant “Volume Peaks,” where singer Bo Orr howls, “And when the volume peaks, then I rejoice.”
