So Solid stepped into the new millennium with a fearsome reputation forged in London's underground scene, and the oversized crew's debut album is a potent mix of slick, electronic garage beats and flashy hip-hop attitude. The MCs take aim at the group's doubters on tracks like the brooding, bass-swamped "Haters." The title track is a stripped-down shot of aggression, while the anthemic "21 Seconds" builds into an epic posse cut that showcases the squad's blazing skills.
