Eight years after the Alc teamup My 1st Chemistry Set earned him widespread attention (and a non-zero number of comparisons to Prodigy), Detroiter Boldy James had refined his flat-seeming flow into a shell-shocked, clear-eyed, beat-riding seance where he calls up his past traumas to shake everyone else in the room. Alc throws in enough left-field tricks of the beat to stymie lesser deadpans, like the brooding-to-panic vibe shift mid-“Double Hockey Sticks” and the unconventional lope of the drums on cuts like “Diamond Dallas” and “Flight Risk.” But Boldy’s nonchalance not only belies his intensity, his relation to the beat highlights his ability to adapt his flow into slo-mo Neo flurries of punch-parrying resilience.
