Béla Bartók, Concerto for Orchestra/Music for Strings, Percussion, and Celesta (BMG). Virtuosic, incisive, commandingly shaped performances by Fritz Reiner and the Chicago Symphony of Bartók’s two orchestral masterpieces, digitally remastered so immaculately that no apologies of any kind need be made for the superlative early-stereo sound. If you find the great Hungarian modernist intimidating, this desert-island CD is likely to change your mind (TT).
