Dev Hynes, a.k.a Blood Orange, has joined forces with Brydon Cook of Starchild and the New Romantic for a collaborative project called VeilHymn. The duo announced the news by debuting a new single, "Hymn." It's a pretty, evocative slow jam that finds Cook—singing falsetto and dropping bars—and Hynes on production and backup vocals. The two are frequent collaborators, as Cook has toured with Blood Orange and contributed to last year's Freetown Sound. Listen below.
