Harmonimix, the more hip-hop- and R&B-oriented pseudonym of James Blake, will soon release its proper debut in the form of a new single for R&S. Blake has previously used the Harmonimix moniker to drop bootlegs of pop hits like Destiny’s Child’s “Bills Bills Bills” and Lil Wayne’s “A Milli,” but is working with Butterz affiliate and grime artist Trim for his new 12″. You can stream the two tracks, “Confidence Boost” and “Saying,” before they’re released this September, below.
