Bone Cracker
Bone Cracker (or Bonecracker) are a band from the city of Minsk, Russia, formed about two years ago. They had a one-track single earlier this year to promote their upcoming debut full length, and that song indeed appears on Пopoku. Apparently this material, and then I am referring to the album and not that single track only, was originally released on tape via Zombi Records.
