the title says all, in this case. "endless black" is a dark glass-harmonium drone that was available in 2010 on alastair's bandcamp. it's never been released in any other format than a mp3-file. the tune of 20 minutes length can not be compared to works like e.g. "orb", "mirrorwork" or "talisman", where songs with lyrics, guitars and violins would prevail.
