Kjetil Mulelid Trio ("scandawegian" jazz trios are a fave)...and hundreds of others...I'm also Mehldau fan, I've run sound for Charlap a few times (lucky me)...Vijay Iyer is astonishing, Tyshawn Sorey (plays with Vijay often) has a killer piano trio album out sort of recently...I'm a piano trio freak.
Some more modern jazz piano trios
Since discovering Christian Pabst several years ago, I've been slowly expanding my catalog of good contemporary jazz piano trios. Among these include the absolutely fantastic Triosence and the equally melodious Yuko Mabuchi Trio. An older artist still putting out immaculately played and recorded albums is Steve Kuhn and his trio.
Any other suggestions?
