Trap music is reverse escapism at its most alluring, overwhelmingly bleak music that nonetheless sucks you into its schizoid world. Rappers who aren’t traditionally skilled can thrive amidst the stuttering snares and Casio strings, because rhyme schemes matter less than successfully projecting a mood; Lil B’s artful artlessness and Desiigner’s off-handed flossing are magnetic. There’s an intimidating, crystalline, harder-than-steel quality to many of the beats on display here: as Rick Ross would put it, color, cut, clarity.
