RCA Victor's Richter Rediscovered lets us hear Sviatoslav Richter perform with intensity and purpose he rarely matched and still more rarely surpassed. This two-CD set comprises Richter's entire Dec. 26, 1960, Carnegie Hall recital and several encores from the same program two days later in Newark's Mosque Theater. Most transcripts of Richter's live performances miss details in his playing--the prismatic shimmer of his tone in all registers, for example, or the way he could instantaneously jump from triple pianissimo to triple fortissimo. But RCA's superb recorded sound does justice to the pianist's variety of nuance and range of dynamics. Younger listeners will now hear Richter "live" the way we older ones remember him: performing Haydn's Sonata No. 50 in C with lapidarian perfection as well as with freedom of rhythm and expression; diversifying, without diluting, the savagery of Prokofiev's Sonata No. 6 by employing softer colors than those usually heard; playing Rachmaninov's Prelude in A with gigantic chords made more all the more impressive by the subtle emergence of the delicate melody from within them; and endowing Chopin's Étude in A flat (Op. 10, No. 10) with breathtaking poetry through ingenious variations of touch and rhythm. --Stephen Wigler
