He's played the Warped Tour on several previous jaunts, opened for Gym Class Heroes and Atmosphere, and sold out headlining shows in venues that typically book indie-rock bands. He doesn't spit rhymes about money or cars or ladies; he samples songs from bands like Fugazi and the Bouncing Souls, and enlists guest singers like the Hold Steady's Craig Finn. He also plays electric guitar onstage while rapping. Plus, Alexander's from Minneapolis (where he co-founded a hip-hop collective called Doomtree), which makes him even harder to classify. P.O.S.'s third album, Never Better, came out in February and helped garner Alexander and his original style more attention and this slot on the Hurley.com stage. — Zemler
