RAVEL: "L'ENFANT ET LES SORTILEGES." Susan Davenny Wyner, soprano; Jocelyne Taillon, mezzo-soprano; Jane Berbie, soprano; Jules Bastin, bass; Phillippe Huttenlocher, baritone; Philip Langridge, tenor; Arleen Auger, soprano; Lind Finnie, mezzo-soprano; Lind Richardson, soprano. Andre Previn conducting the Ambrosian Singers and the London Symphony Orchestra. EMI-Angel Compact Disc CDC 7 47169 2. This is not the mysterious, magical performance one might expect. Instead, Previn gives us a straightforward, no-nonsense account in vivid, crystalline sound. The CD sound is particularly appreciated with Ravel's flowing music since details of his subtle orchestration sometimes get lost in analog reproduction. The orchestra, chorus and singers (with the exception of Wyner's ragged voice) perform admirably.
