From the musicians involved I witnessed in performance Pat LaBarbera with the Elvin Jones Jazz Machine in the early 80`s and Neil Swanson (with Woody Shaw in mid/late 80`s ?) .... would have loved to see Don Thompson (both on b or b) though ....
Live in Switzerland 1975 is excellent .... Bill Evans + Eddie Gomez in near perfect synch and Eliot Zigmund unleashes waves of delicate drumming .... btw the recording (by Swiss Radio) is very good ....
