UK dronemakers Bradley and Wells had already published each other on their respective label (Bradley's little gem "Immure", on Wells' sadly defunct Locus of Assemblage, also being my first exposure to his soundscapes), so it's only logical that they now carry out this collaboration/split project, both using and mixing each other's material. Oddly enough, Wells sounds a lot like Bradley and vice-versa, which made me wonder if I had got the track list right. Wells' "Op. 5" is a very austere and convincing piece of vaguely metallic drones, low-end tones and looped field recordings, while Bradley's "Heart of Embra" is based on similar elements, but in a more fragmentary and collage-like way, with field recordings soldering the various movements - much in the wake of Wells' contribution to the "Drone Works" series. I slightly prefer the first piece, which sounds more cohesive, but the second one has a nice cinematic quality, which also proves Bradley's dexterity at mixing. Fans of both artists take note - there is also a new full-length work by Wells in the pipeline.
