What’s the statute of limitations on a “late pass”? Six months? One year? Because Philadelphia rapper Tayyib Ali’s Keystone State of Mind mixtape, from whence this song originates, came out so long ago that he’s already got a sequel out. (Both of them are available from online mixtape palace DatPiff.) An clearly Ali isn’t exactly “undiscovered,” not if his 18k Twitter followers are to be believed. But we’re risking looking foolish and posting this anyway, because it’s so instantly winning, a hazy chipmunk-soul loop supporting Ali’s earnest, on-the-beat rhyme style.
