Some suggestions for Don Satz, some no doubt NLA:

Bach-Busoni:
Peter Rosel, Capriccio
Nikolai Demidenko, Hyperion
Maria Tipo, EMI (Interesting for those concerned with performance
"lineage".  Tipo was trained by her mother, a Busoni pupil) Buechner,
Connoisseur Soc.  (Includes "world premiere" of Busoni's arrangement of
the Goldbergs)

Other works:
Geoffrey Tozer,Chandos (various, incl. Fantasia nach Bach, Indian Diary)

Bruce Wolosoff, Music & Arts (Sonata f minor, 7 Elegies)
Valerie Tryon, CBC (Carmen, Indian, 6 Short pieces, some Bach)
Claudius Tanski, MDG (4 Elegies, Toccata, some Bach)
Christpher O'Riley, Centaur (Fantasia Contrapunt.)
Jos. Banowetz & Ronald Stevenson, Altarus (Fant. Cont., other 4 hands
pieces)

I second the recommendations of Ogden & Jacobs-Oppens for Fant. Cont.

I find the Concerto a real snoozer, but Hamelin is presumably the one to
have.
