On February 27th, Detroit's Boldy James will release Consignment: Favor for A Favor (The Redi-Rock Mixtape). "Oil Sheen (Grease Monkeys)" is the second leak from the project, following last week's "Consignment." It features Chicagoan Fatboi Fre$h, who had a verse on Boldy's 2011 track "Truck Driving School," and released an EP of his own, Escape from Fat Camp, just days ago. "Oil Sheen (Grease Monkeys)" has an unusual feel thanks to producer M. Stacks. Its sample is distorted with percussion rattling around like coffee percolator, wedded to titanic drums. But it's Boldy's dusty voice, the rapper vocal ideal, that leaves the strongest impression.
