"September 2000, at the instigation of producer Gert-Jan Blom, Basta Music obtained the license of the 44 master-tapes containing Gurdjieff's complete recorded output from Mme. Sylvie Anastasieff, widow of Valentin Anastasieff, Gurdjieff's nephew. The 113 recordings on these tapes were sequenced in four series: I: First Series - recorded between 1 April and 21 July 1949 II: Mesoteric Series recorded between 22 July and 18 August 1949 III: American Series -recorded between 25 August and 27 September 1949 IV: Second Series -recorded between 27 September and 16 October 1949. These were recorded at Gurdjieff's apartment in Paris. Additionally, the very first recordings of Gurdjieff's harmonium music - made at the Wellington Hotel, New York, between 25 December 1948 and early February 1949 - have been added to this collection with the consent of the Gurdjieff Foundation of New York. These New York recordings also include several talks and stories as told by Gurdjieff."
