For the time being, the Disquiet Downstream remains focused on freely downloadable music, but exceptions should be made for the occasional noteworthy streaming-only release. In this case, for the past week or so the background track at the website of Autechre‘s record label, Warp (warprecords.com), has been “Fermium,” a track off its forthcoming album, reportedly titled Untitled, due out April 18 in the U.S. The track, which repeats at length a short glitchy rhythm before breaking off into dubby abstraction, has received some airplay, though it’s not yet commercially available; it appears on the February 17 playlist of BBC DJ Rob da Bank (here), slipped between the Wedding Present and Lady Sovereign.
