the gold standard is of course bill evans’s trio, especially the seminal recordings with scott lafaro and paul motian
in more recent times keith jarrett with gary peacock and jack dejohnette approach the prior standard (don’t skip the deer head inn album with paul motian sitting in for jdj)
brad mehldau’s trio is even more recent times is also quite excellent, and sets a high standard (grenadier and ballard)
chick corea’s trilogy albums are also stupendous (mcbride/blade)
i would also suggest listening to swedish pianist bobo stenson’s trio work with anders jormin on bass, with various drummers, on ecm, which is outstanding - absolutely transcendant beauty
