I hope it's OK to include two Jewish non-professional musicians, Alan Rose and Paul Woodrow.
Alan Rose, who is from Leeds, England, won a young British jazz pianist contest in the 1960s. The prize was a week in New York City, with visits to jazz clubs and an appearance on television, sitting in for one number with Al Cohn/Zoot Sims. Recalling it recently, he told me Jimmy Garrison was on bass and Gus Johnson on drums and the number was a twelve-bar blues (of course!)
Paul Woodrow, originally also from Leeds, but now long resident in Calgary, Alberta, plays both modern jazz piano and blues keyboards. He names Victor Feldman, Carl Perkins and Wynton Kelly as his favorite pianists. He currently plays keyboards with the Rooster Blues Band, based in Calgary. Here they are backing blues singer Lou Pride in Boston:
