Review: James 'Fucking' Friedman reckons that in the three years since Moon Rock Volume 1 came out on his New York City based Throne Of Blood imprint, interest and attention in ambient and cosmic music has broadened and deepened. Well, hey that's a fair call and with Moon Rock Volume 4, the label is once again rounding up a shitload of weird-ass kosmische sounds. According to the label, the compilation was conceived in sides; six distinct sets of music that move through a range of styles and sounds, from chill ambient excursions to darker droning noise. Danny Passarella's imaginary soundtrack "Carousel Rising"is guided by a clever use of arpeggio, Tel Aviv indie dance hero Moscoman impresses as always with more cosmic weirdness on The Edge Of The Earth" while Versatile Records legend Gilb'r presents "Arpeggio Island"which doesn't need much explanation. London duo Vactrol Park impress as always with another deep vintage synth exploration on "Islands Of The Delta".
