Stoned teenagers are responsible for some of the best hip hop ever made. The wise sages of today were the blunt-rolling kids of 10 years ago, and by that logic precocious Chester Watson could have a great album in him someday. His new tape, Past Cloaks, is not an album proper, but it’s pretty great nonetheless: woozy and dense, hyperverbal and unintelligible, simple yet complex. But Watson himself is a terrifically wordy millennial who compiled Past Cloaks from his recent run of mixtapes. He hails from Florida, but his music bears little resemblance to the trap music that dominates Southern hip hop.
