Dave Doyen gets rough with his modular synth setup on this burner, a 28-minute trip that leaves scorched wreckage in its wake. Different in temper and feel from earlier Vales releases on labels like 905 Tapes and Ghetto Naturalist Series, Boreal Head Trip finds Doyen working with sharp-edged and brittle tones. Vales may have moved into harsher realms but Doyen's sense of development keeps things intriguing throughout this journey into darkness. Edition of 100, pro-dubbed. $7 ppd. US, $12 ppd. rest of world.
