The music conceived by Miles Davis and Gil Evans between 1949 and 1950, and released in 1957 on Capitol records marks an important new step in Jazz. Featuring an unusual line up and innovative classical oriented arrangements, this historical album represents the birth of a new form of Jazz. For the occasion Davis and Evans display a stellar nonet including, among others, Lee Konitz (alto sax), Gerry Mulligan (baritone sax), John Lewis (piano) and Max Roach (drums). The result was an unprecedented and highly sophisticated form of music which would be subsequently called "Cool Jazz".[info from label]
