Oscar Pettiford was the first major jazz figure to take up the cello, playing cello on at least 10 LPs over a 10-year period. His first recording with the cello, "Great Times," was made in 1950 with Duke Ellington and a small combo.
The next important jazz cellist/bass player was Ray Brown. He found the cello "such a nice, easy and clear means of expression." Brown recorded "Jazz Cello" and "Ray Brown and his Jazz All Star Big Band." Other bass players who played and recorded jazz on cello include Harry Babasin, Sam Jones, Eldee Young, Percy Heath and Keter Betts.
In the mid 50's Fred Katz was perhaps the first trained cellist to play jazz. He introduced the use of the bow in jazz cello playing. This added a much wider range of timbres and effects and a new sense of swing to the palette of the jazz cellist. Katz played melodies, harmonies, solos and wrote arrangements for drummer Chico Hamilton’s chamber jazz groups.
Jazz bassist Ron Carter's first instrument was actually the cello. In high school he switched to bass and went on to study at Eastman. After getting involved with jazz, he brought the cello out again (tuned in 5ths). In the 60’s he played cello, with the bow, on albums by Eric Dolphy, Mal Waldron, and George Benson.
