WORLD PREMIÈRE RECORDING The Lorelei Rock in the Rhine River on which the siren Lurline played her enchanting harp to lure fishermen to a watery grave is the setting for Lurline, heard here in a new performing edition by Richard Bonynge. Victorian theatre critics declared it an outright success and the opera played for a substantial number of performances, making it a landmark production. Wallace’s melodious score is even richer than that of his earlier opera, Maritana.
