For those who might be interested, the recording to which I referred is still in print. It's "Water Music of the Impressionists", played by Carol Rosenberger on the Bosendorfer Imperial Concert Grand. I first bought it on vinyl (!). The selections are all solo water-themed piano works by Ravel, Debussy and others. One track, "The Sunken Cathedral", uses the extra bass keys very effectively. Highly recommended on CD or vinyl.
