My discography of saxophonist Herb Geller is available in 3 parts at: http://www.attictoys.com/jazz/HG_intro.html
This could be used as a source of data to be entered into J-DISC. It includes famous sessions by Clifford Brown, Dinah Washington, Ella Fitzgerald, Shorty Rogers, Chet Baker, Bill Holman, Maynard Ferguson and many others. The third part covers his European years starting in 1962 and includes many sessions with the NDR Bigband and Peter Herbolzheimer. Geller worked at NDR for 28 years.
