SOS is finally here. Five and half years after Ctrl — during which SZA voiced frustration with her label Top Dawg — and days after announcing the release date on SNL, the R&B star has released her sophomore album. It boasts guest spots from Phoebe Bridgers, Travis Scott, Don Toliver, and Lizzo (who has an uncredited feature on “F2F”). Ol’ Dirty Bastard’s “The Stomp” and Björk’s “Hidden Place” are both sampled on “Forgiveless.”
