Beautiful copy of the 1961 first pressing of Stockhausen's Zyklus and Refrain, released on the Time Records Series 2000 label, 58001. Also includes Kagel's Transición II, all performed by the quartet of David Tudor, Christoph Caskel, Aloys Kontarsky, and Bernhard Kontarsky. The disc is very nearly perfectly mint and plays flawlessly and just beautifully. The cover only has the slightest shelfwear. A top original copy, and one of the great early recordings of Stockhausen.
