Mu (album)

Mu, First Part and Second Part, is a pair of albums by American jazz musician Don Cherry. The albums were recorded in a single session on August 22, 1969, at Studio Saravah in Paris with drummer Ed Blackwell, and were released by BYG Records as part of their Actuel series in 1969 (First Part) and 1970 (Second Part). In 1971, BYG released both parts together as a single box set. Mu was one of the first efforts in what would come to be known as world music.

In December 1977, Cherry and Blackwell presented a concert at New York University called "Mu, Part Three."
