Steve Roden and Stephen Vitiello are old friends, having previously collaborated on live projects (a recording of a 2007 performance in Texas has been doing the rounds for some time). Here, the two sound designers and experimentalists join forces once more for their first studio collaboration. The Spaces Contained in Each is perhaps typical of each artist's solo work. Comprising of a single, 49-minute track, it melds ghostly ambience, electronic interference, occasional samples (a church bell here, footsteps there, delay-laden train noises drifting in and out of the mix) and droning textures to create a calming but occasionally unsettling collage. Beautifully designed and produced, with superb stereo panning, it's an immersive - if low-key - treat.
