It wasn’t even a year ago that we wrote up UGK’s first album since Pimp C’s release from prison. Vibrant and celebratory, it was a terrific comeback. But Pimp C died in December, from an accidental cough-syrup overdose, and left partner Bun B flying solo. Morose, accusatory, and nostalgic, II Trill is a heavy slab of Bun B’s psyche on wax — but more important, a better than worthy tribute, even without the invocations of Pimp C’s spirit.
