You don’t listen to KA albums so much as you sink into them: the hushed, laser-focused flow, the dense imagery and virtually drum-free production, the sense of darkness lurking quietly around every corner. Loosely organized as a metaphorical play between Cain’s murder of his brother Abel and KA’s own violent memories of youth in east Brooklyn, Descendants of Cain is, yes, deadly serious and noir to the marrow. But between the whiplash-worthy observations—“All our Santas carried them hammers/Our guidance counselors was talented scramblers” (“Patron Saints”), “The meek heard ‘turn the other cheek’/I got different advice” (“Solitude of Enoch”)—is a sense of almost meditative calm, the sort of resolve that comes not from the heat of youth but from the steadiness of middle age. The pace is measured, the tone is cool, but the past still haunts him.
