Description Ultra Rare!! Note the stamp on the label – Courtesy of Gargoyle International. This promo was sent to an industry insider who Gargoyle was trying to get to promote some action in the US. This is the original German 70s Pressing of the only album by GRAIL, a UK PROG Rock Psychedelic Crossover group. Apparently no one would release it in the UK, but Germany’s Metronome label released it in the very early 70s. Most interesting, it was produced by Rod Stewart!!
