Pinch and Photek most recently shared a byline last summer, when Photek served up "Closer," the 50th release for Pinch's Tectonic Recordings, a record which also featured Pinch as a remixer. In two weeks, the veteran producers will pair up again to release a collaborative single, "Acid Reign (Pinch's Dubplate Version)" b/w "M25FM." (You may recognize "Acid Reign" from Pinch's Fabriclive 61 mix.) This time, the two acidy bass numbers will be released through Photek's imprint, Photek Productions. The single comes out on March 12, but you can preview both tunes below, and take a look at the artwork above.
