Electronic Music For Two Ballets

From the liner notes: "Towards the end of his life, Ernest Berk gifted his entire collection of works, tapes, documents and all to the Historical Archive of the City of Cologne. Tragically, in 2009, a large part of the archive collapsed (due to the construction of an underground railway) destroying 90% of everything. Berk’s tapes have tragically never been recovered. They are assumed lost forever. So these two recordings – issued privately circa 1970 – remain precious to say the least. There were no masters, this new pressing was simply transferred from the original copy held by his family. We have done our best to restore the sound."
