definitely the köln concerto. it totally opened my eyes and ears to a new way of interacting with classical instrumentation. he really gets into the guts of the piano, pulls the strings with his hands, hits it percussively, grunts and moans and almost humps the thing, it's an amazing record and quite beautiful, too.
You can't mention Jarrett without mentioning Bill Evans really can you?
A good modern piano player is Brad Mehldau - his Art of the Trio series is part of a direct lineage through Evans and KJ. He has being doing solo stuff of standards and takes on modern songs (Radiohead and Nick Drake for example) without being wacky - much in same the way that Evans did with things like Paul Simon's I do it for your Love and Theme From MASH in those graet late albums. He also has been working on original compositions which are virtuoso performances.
We had a really nice piano players thread a while back - lots of real expertise shown by people who know much more about this stuff than i do.
Funny that you mention Mehldau, Jenks. I just dug up his first solo LP "Elegiac Cycle" this week, and have been playing it a bunch. It occasionally veers into the sententious, but definitely has many lovely moments.
I just downloaded a pretty rad avant-y jazz piano "mixtape" compiled by Vijay Iyer here, but it seems that they've taken it down. I'll re-up if anyone's interested.
Keith Jarrett and Gary Burton is lovely if you like vibes - I'd like In Your Own Quiet Place played at my funeral. Aaaaaaaaaaaaaw. Are you allowed nine minutes of tinkly-pinkly jazz? I do hope so.
Bop Be is a load of boring old shit if you ask me.
