F**king with Chamillionaire is a little like grabbing a straight razor by the wrong end; you’re guaranteed to come away with some deep cuts, and you very well may find end up in the emergency room. On newly-released promo single End of a Knife, however, the H-Town mainstay gets blood on his hands without even intending to do so. Accompanied by Kato‘s Latin guitar, strings and pensive keys, Cham describes a love triangle involving himself, his roommate and a two-timing shawty, each of whom is deceiving the other two. This skillfully-crafted narrative jam isn’t attached to a larger body of work, but we’ll keep you posted on the Chamilitary man’s plans as further details emerge. In the meantime, why not take a listen to his last DJBooth feature, this month’s Go Getta?
