Mozart: Complete Variations and Other Works for Solo Piano
Walter Klien is particularly outstanding in stuff like this; for him, no Mozart was without consequence, and he approached every note of this music with care and inclined toward a lucid, yet relaxed and no-nonsense approach. Klien is in his absolute best when there's a challenge afoot, as in the Eine kleine gigue in G, K. 574, or the fragmentary Klaviersuite in G, K. 399, from the 'Bach year' of 1782. But even in relatively unchallenging works, such as a handful featured here with 'K.' numbers lower than 100 and therefore composed before [Mozart turned 15], Klien imbues them with a sense of dignity and occasion, even if the music is not particularly distinguished. --All Music Guide
