"We know now we want more/ A life worth fighting for," Santigold dazedly drawls on "Disparate Youth," the standout track from her sophomore album. And she fights hard here, after four years of writer's block and touring burnout, getting Karen O to crash the party on the militaristic dub-punk opener "Go!" and snatching writing and production help from such A-listers as Dave Sitek, Boys Noize, Q-Tip and Major Lazer's Switch and Diplo, whose apocalyptic, bass-heavy dancehall dominates much of the album. Meanwhile, Santi herself sizzles with sass and spunk on songs like "Fame" and "Freak Like Me."
