エニグマ変奏曲
Ibbs and Tillett was founded by Robert Leigh Ibbs and John Tillett, who trained under impresario Nathaniel Vert (Narciso Vertigliano). It was Vert who, as Edward Elgar's concert manager, sent Elgar's "Enigma Variations" to another of his concert management clients, Vienna Philharmonic Orchestra conductor Hans Richter, who premiered the work in London in 1899.
