Budo is a Miles Davis composition co written with Bud Powell, named as a tribute to Powell. It originated in the Birth of the Cool era, recorded January 21, 1949 in New York and released on The Complete Birth Of The Cool in 1957. The tune belongs to the cool jazz genre and is performed by a nonet that includes Miles Davis on trumpet, with players like Lee Konitz and Gerry Mulligan among the others. Budo is notable for its restrained, textural approach and subtle harmonies that define the Birth of the Cool sound. A remastered version was released on May 19, 1998, and there is also a live version titled Budo (Hallucinations) recorded at the Royal Roost in New York on September 18, 1948.
