I'd like to send another big "thanks" to everyone who gave suggestions. I received an order yesterday with two LP's suggested on this thread - Nojima Plays Revel (RR label) and Rubenstein's Chopin: Preludes Op. 28 (RCA). While these are both excellent renderings, I especially like the Nojima LP ... very well recorded, relaxing, with great piano work. This is just what the doctor ordered. It's a great start and I'll probably pick up 2 or 3 albums. The Rubenstein piece (though not exactly as recommended) is quite nice in a general sense. It is reminiscent of an excellent CD recording I picked up as a result of another A-gon posting that discussed great piano work:
