With his latest side project, political hip-hop icon Boots Riley has taken the advice of The Coup’s last album title and picked a bigger weapon: the beastly electric guitar of activist and Rage Against The Machine-ist Tom Morello. Commercially, Morello’s signature sound is huge; it’s the engine that put millions into corporate coffers backing up Zack De La Rocha’s capitalism-bashing vitriol. It’s just as huge sonically, an arena-ready weapon of mass sonic destruction. Alas, in Street Sweeper Social Club, it’s arguably too fucking big: Riley’s literate storytelling and gentle humanism get trampled under the airplane-engine roar of Morello’s thundering riffs.
