Red-hot production duo Christian Rich - Chicago-born, LA-based twin brothers Taiwo and Kehinde Hassan - played a prominent role on Earl Sweatshirt's landmark's 2013 LP, Doris, and can also put their name to the likes of Drake and Childish Gambino, among others. Now they've turned their attention to multi-disciplinary artist/singer from Atlanta, Bosco. Sharpening the edges of her honeyed r'n'b coo with trap-powered hi-hat trills, their reworked offering of Bosco's Gold Ghost presents itself as a high-art, progressive pop experiment which will have you thinking long and hard about the possibilities of sound and production. -AW
