Hello - I'd like to think I had a hand in the re-release of the Deutsche Grammophon (DG) avant garde series of recordings, originally released between 1968 and 1971. I e-mailed DG and suggested the re-release and recieved a reply along the lines of "I will forward your idea on." This set comprises of 21 compact discs. Some of the original releases have not been included at the request of the Karlheinz Stockhausen estate, as they now release the recordings on their label - Stockhausen-Verlag .
