The drawback to this comprehensive feast of prime Vladimir Horowitz is EMI's overzealous noise reduction, which smoothes the edges off of the great pianist's unique sonority. This is less bothersome in the 1951 sessions, which produced two delicious Scarlatti Sonatas not reissued elsewhere. The high-voltage Horowitz of the thirties was a more direct, less mannered artist than his older self. But his classic Liszt Sonata, Chopin Fourth Scherzo, and other solo EMI jewels are best heard via APR's superior (albeit more expensive) transfers. This erratic but exciting Rach 3 (with cuts, and a momentary third movement memory lapse) still awaits a CD transfer to match that of a bygone Seraphim LP. --Jed Distler
