bloodpop, formerly known as BLOOD, formerly known as Blood Diamonds, has now teamed up with DJ Dahi under the name DiamondDahi. They’ve worked together to produce tracks for people like Big Sean, Lupe Fiasco, Tinashe, and Madonna, and now they’ve dropped their first official collaborative single, “N.M.B.D.” — which stands, fittingly, for No More Blood Diamonds. It features vocals from British rapper Little Simz, and you can hear it below.
