Helledéofol
Quite the only thing I do know about Helledéofol is that they hail from the U.K., but do not ask me who is / are the (human) being(s) behind the project, for I do not know. In 2015 they did release some material on tape and the digital way, and early 2016 sees the release of Black Acid, the newest release, available the digital way on their independent (or Bandcamp) page, and in an extremely limited edition (of 25 copies only) on cassette via the young UK-based label X-Ray Noise.
