Some of my favorites:
Albert Mangelsdorff Quartet – Never Let It End (MPS, 1970)
A superb group with Heinz Sauer (ts, as), Günter Lenz (b), and Ralf Hübner (d)
Eddie "Lockjaw" Davis & Johnny Griffin – Tough Tenors Again 'n' Again (MPS, 1970)
with the CBBB rhythm section: Boland, Jimmy Woode, and Klook
Eddy Louiss – Our Kind of Sabi (MPS, 1970)
with fellow Euro-all-stars John Surman and Daniel Humair
Attila Zoller/Masahiko Sato – A Path Through Haze (MPS, 1972)
A gorgeous record, not one false note
Joachim Kühn – This Way Out (MPS, 1973)
Kühn's group was perhaps inconsistent, but also pleasingly different, self-consciously European
Hannibal & the Sunrise Orchestra – Hannibal (MPS, 1975)
An under-recognized classic of 1970s jazz
John Handy & Ali Akbar Khan – Karuna Supreme (MPS, 1976)
A West-Meets-East pairing that actually works well
Martial Solal – Suite for Trio (MPS, 1978)
with NHØP & Daniel Humair; all of Solal's MPS recordings are terrific, but this is my desert-island pick
Joe Henderson – Mirror, Mirror (MPS, 1980)
with a dream rhythm section: Corea, RC, and Billy Higgins
Lee Konitz & Martial Solal – Duo: Live at the Berlin Jazz Days 1980 (MPS, 1982)
Pure improvisation -- and the finest of their many recorded collaborations, IMO
