Watch SD's "Circles" Video

For the past few years, Chicago's SD has been the secret weapon of Chief Keef's Glory Boyz Entertainment. The three installments of his Life Of A Savage mixtape series are some of the strongest full-length drill projects to date, featuring his excellent Danny Brown collaboration "New World Order." He's gearing up to release his debut album, Truly Blessed, later this week, and shared an ornate video for its first single "Circles." It's a heavy, grungy track that represents an intriguing new direction for the rapper, somewhere between drill and nu-metal (don't worry—the result is way better than that description sounds). Truly Blessed is out November 18 on iTunes.
