Another nice one is Mike Nock's Trio "Not We But One" on Naxos: https://www.discogs.com/Mike-Nock-Trio-Not-We-But-One/release/4153597 . Cox is very prominent here. I think the drummer Tony Reedus is needlessly hyperactive here, but it's a nice record nonetheless.
I have Cox's solo on Sketch. Haven't listened to it in ages, but I do remember finding it good but not great. The sound is excellent, but does not have the range of ideas of the best solo bass records (like the ones from Barre Phillips or Joelle Leandre or Mark Dresser or Paul Rogers), IMHO.
