Specially-priced 4-CD set reprising the history-making recordings Chick Corea and Gary Burton made for ECM in the 70s. The duo was a seldom-tested format in jazz when the musicians - at the instigation of producer Manfred Eicher - came together for Crystal Silence, but its luminous music proved a resounding success. Both Duet and the Zürich recordings won Grammy awards, and Corea/Burton have continued to make music together for 35 years! This box shows how the story began. Two live selections I"m Your Pal/Hullo, Bolinas and Love Castle appear on CD for the first time in this collection. The booklet includes liner notes by acclaimed Swiss journalist Peter Rüedi and writer Steve Lake, and many archival photos.
