A swarming, enveloping torrent of guitars; a crashing tidal wave of drums; a wordless might. Red Sparowes — comprised of members from bands like Isis, Halifax Pier, and Angel Hair — make a relentless brand of post-rock and their third album, The Fear Is Excruciating, But Therein Lies the Answer is its boldest yet. "A Hail of Bombs" comes on like a lurking giant; slow and quiet first but inevitably pummeling. Combine their typically fist-clenched intensity with a cascading melody and you've got one of the L.A. staples' very best yet.
