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 BlackTar 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 as 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.
