Following the release of their most acclaimed album of their decade-long career, Deep Politics (2011), Grails revisited Black Tar Prophecies, their ever-expanding, enigmatic tapestry of eclectic experiments released in scarce limited editions that often disappear before most fans discover their existence. Black Tar Prophecies Vol's 4, 5 & 6 collects the last three volumes in the Black Tar series, originally released as a limited-edition 12", and a split LP with Finish psych-rock phenoms, Pharaoh Overlord. Exclusive to this collection is Volume 6, three previously unreleased tracks that run the gamut from found-sound collage to moody, piano-driven soundtracks to obscure erotic horror films that never existed (but should have). Available on triple-gatefold CD Digipak or Deluxe Gatefold 2xLP, the vinyl features four mind-blowing laser etchings – one on each side of the record, beginning where the grooves of the music end. It's pretty, and pretty unbelievable.
