Alan has recommended Jacques Loussier Trio's The Best of Play Bach, and I was just listening to it earlier today. While I usually don't have the patience to listen to the whole thing (can't seem to fully embrace jazz), I would agree that it's a great recording. Oh, I should note I have the SACD, so I can't vouch for the normal CD. Another SACD which I do enjoy listening to in its entirety on occasion is Marta Gómez's Cantos de Agua Dulce. I believe PeterChenoweth recommended that one, and it is certainly a recording I use to show off my system.
