Pianist Chick Corea and vibraphonist Gary Burton became a collaborative team almost by accident. Their first musical encounter took place at a Jazz festival in Germany in 1972, when they performed together in a spur-of-the-moment encore. The results were so satisfying – not only to the audience but to the artists themselves – that the two musicians reconvened in a recording studio a couple months later to record the intricate yet highly melodic Crystal Silence, their first of several collaborative studio projects.
