Leonard Bernstein's performance of Copland's Third Symphony has had to wait a long time before finally appearing on CD. Part of the delay no doubt stemmed from the fact that DG released a second, later recording with the same orchestra, in digital sound. Comparing the two versions, both of which are very good, one prefers this first performance. Not only does the music move a bit more quickly, with sharper rhythms and a stronger sense of the dance (never far from Copland's musical thoughts), but the sonics are more naturally pleasing. The coupling is a terrific performance of the early Organ Symphony, which the composer wrote for his teacher, Nadia Boulanger. --David Hurwitz
