Hm, let's see ...
Cecil Taylor & Tony Oxley, Leaf Palm Hand
Tomasz Stańko, Leosia (as well as Bosonossa and Other Ballads by the same quartet)
Derek Bailey & Tony Oxley, Soho Suites
Tony Oxley Quintet, The Baptised Traveller (OOP and often hard to get at decent prices, unfortunately)
Joseph Holbrooke Trio, The Moat Recordings
Evan Parker / Cecil Taylor / Barry Guy / Tony Oxley, Nailed
John Surman, Adventure Playground
Bill Dixon, Vade Mecum (Vols. I & II)
John McLaughlin, Extrapolation
I see he also appeared on those Gordon Beck albums you recently listed - I haven't heard those.
Know and cherish most of those ... came too late to have all the CT FMPs, alas (I have hardly any, they oughta be reprinted, but with that longtime war between the former or never really or who the eff knows what ... "partners", it's rather unlikely anything much will be back ... but in a week I'll be in Munich and one of the plans is to visit the exhibition on FMP at Haus der Kunst) ...
Managed to catch Oxley live in duo with Cecil Taylor over ten years ago (autumn 2006 I think) - that was amazing, though i botched it a bit (left a bit early to catch the last train home, missed it, still had to stay the night though, but a friend told me I missed only very few more minutes ...)
Anyway, some more:
Anthony Braxton - Seven Compositions (Trio) 1989
Bill Dixon - Papyrus I & II (just get that Bill Dixon Soul Note/Black Saint box, folks!)
Alan Skidmore - Once Upon a Time
Cecil Taylor Feel Trio - Two T's for a Lovely T (live, 10 CD box, two sets over five nights, glorious!)
Alan Skidmore / Ali Haurand / Tony Oxley - S.O.H. (reissued in one of Organic Music's EGO recordings boxes)
He is also drumming on various british larger band recordings such as:
John Surman - How Many Clouds Can You See?
Kenny Wheeler - Song for Someone
Michael Gibbs - Michael Gibbs
and of course several of Barry Guy's LJCO recordings on Intakt
Re Gordon Beck (don't know him all that well yet), Oxley is on this MPS oddity (I have it on vinyl, prob. not on CD):
Gordon Beck / Ron Mathewson / Tony Oxley / Stan Sulzmann / Kenny Wheeler - Seven Steps to Evans: A Tribute to the Compositions of Bill Evans
