I only have one Fischer album, Extension, a 1963 Pacific Jazz lp [PJ-77].
I see that it was finally released on cd coupled with a dubitable mid-70s Songs For Rainy Day Lovers. The title of the cd is America The Beautiful...
Extension is quite great. Pleasant low key compositions and arrangements and a primo big band [bud Shank, Sam Most, Larry Bunker, et al]. With just the right touch of Afro-Cuban. A scarcely recorded Jerry Coker and Fischer are the only soloists. On alto Coker sounds like a magna cum laude Lee Konitz disciple.
A not to be missed album, imo.
Fischer was affiliated with Cal Tjader in the late 50s, perhaps later as well.
