Drum & bass innovator Rockwell has announced that he will be releasing a new EP, User, on Feb. 16, and today we've got the exclusive first play of one of its highlights: "Inventor", featuring the bars of Flowdan. It's a bit of a surprise the two haven't worked together before this, with Flowdan's deep, gruff bars and Rockwell's big, noisy, jungle breaks working so well together. Elsewhere on the project, there's a Roni Size collab, and a few different tones of D&B. Take a listen below and keep an eye out for the EP when it drops.
