When Florida rapper/producer and evil old-school fight-music revivalist Spaceghostpurrp released Mysterious Phonk, his official debut album, earlier this year, a lot of the chatter revolved around how he’d cleaned up his sound, removing many of the lo-fi rasps and random noises that made his earlier mixtapes so disorienting. Today, Purrp released his new mixtape B.M.W. — he’s calling it an EP, even though it’s 14 songs long, and the titular initials stand for Black Man’s Wealth — and at first listen, it brings back much of his old queasy lurch.
