André Previn’s ’70s recordings of the Tchaikovsky ballets are a cornerstone of his widely followed conducting career. His lucid and flowing way with the LSO during Swan Lake shows precisely why: Beyond tending to the familiar melodies, Previn and his players lavish attention on the less familiar motifs and dances from the full work. Still, the showstopper moments come off well (check out the stomping “Coda” from the Act I “Pas de deux”), as do the tender moments (like violinist Ida Haendel’s solo during “Danses des cygnes”).
