the current technical perfection makes the difference sometimes these old waxes trying to listen but slow movements especially awaiting the next note is sometimes .... hardly sustainable, and forget all the failures of Schnabel, the age of the record (and that of the lady !!!), the relative weakness of the inspiration for some songs, .....; it is at times shockingly beautiful! the prominent place of these sonatas of Beethoven in the work certainly deserves to multiply the integrals references as isolated versions but for lovers of these pieces, Schnabel is a must if not essential.
