Christian Rich, the duo comprised of Nigerian brothers, has dropped off their newest single, "High." As producers, the two have become deeply embedded in the music industry, especially on the left coast: their credits include songs on Doris, Earl Sweatshirt's debut album, as well as credits on Childish Gambino's Because the Internet, J. Cole's Born Sinner and more. (This is to say nothing of the studio musician work they contributed to Drake's 2013 record, Nothing Was the Same.) Now, they enlist Vince Staples--one of the genre's brightest young stars--to bring "High" to life. His vocals, along with Bia's, benefit from the track's ceaseless forward motion.
