Chuck Israels' sideman duties make for impressive reading. Most jazz bass players would give their eye teeth to have chalked up anchor roles with the likes of pianist Bill Evans, saxophonist John Coltrane, pianist Herbie Hancock, saxophonist Stan Getz and diva Billie Holiday. But, for 73-year-old Israels, who will be in this country next week for a three-gig tour, anchoring the efforts of stellar frontliners was never enough, especially when fusion came along in the Seventies.
