ACRE "Volcanic Legacy" (Bone Tooth Horn)

This one came in a batch with several other Bone Tooth Horn (NJ) releases which will hopefully be worked through for CG soon. Check out the sites below anyway, if not just for the new promotional photo/shrine.
Most anyone with a soft spot for minimal oscillator-driven drone would lap up this trance-inducing 40 minute slothfest from Portland's Acre. The two side-long tracks, "Riley" and "Volcanic Legacy," offer subtle differences in harmonics but more or less all material on here is produced with the same formula. Following a slow build, the tones contort into a simultaneous lull and euphoria. Simplicity like this isn't necessarily easy to pull off, but Acre provides a good example of how it's done. RECOMMENDED!
