With the "Bop Shots" band, he took his first steps in the jazz world. In 1950, Jaspar moved to Paris, playing and recording with the best musicians of the era. Here he met singer Blossom Dearie;[1] the two were married in 1954 but separated in 1957.[2]
In 1956, Jaspar was persuaded to try his luck in the United States, where his reputation in jazz circles had preceded him.[1] He played and recorded with the quintet of J. J. Johnson, with Kenny Burrell, Miles Davis, John Coltrane, Toshiko Akiyoshi, Donald Byrd and many others.[1]
In 1961/1962, Jaspar returned to Europe for a year for a series of concerts and a number of recordings, and formed a successful quintet with Belgian guitarist René Thomas.[1] In some sessions, this was expanded to a powerful sextet with American trumpeter Chet Baker. One of those sessions, recorded in 1962, was released on record as Chet Is Back!.
