Anything by Mikhail Pletnev, the Russian pianist. His recording of "Pictures From An Exhibition" on Virgin is stunning. I can't stand the orchestral version of Pictures...the original piano version is vastly superior.
Two other Pletnev recordings well worth having are his Scarlatti sonatas (on piano, not harpsichord; also on Virgin, I think) and "Live at Carnegie Hall" on DG.
Pletnev, in my view, is equivalent to another Russian great, the late Emil Gilels.
