The latest in our Music Now & Then series with composer Liza Lim, who first appeared on The Music Show in its early years when she was in her mid twenties, where both her youth and the 'difficulty' of her music were remarked upon. As her opera The Oresteia is remounted by Sydney Chamber Opera and ELISION Ensemble, Andy speaks with Liza on stage about revisiting works and ideas over more than thirty years. The Oresteia is staged at Sydney's Carriageworks 24-31 July.Music heard in the show:Title: The Oresteia: The Furies; Positions of a memory theatre (Cassandra’s Dream Song); Athena’s TrumpetArtists: Jeannie van de Velde, Julie Edwardson, Deborah Kayser, Andrew Muscat-Clark, Tyrone Landau, Grant Smith (singers), Elision Ensemble/Sandro GorliComposer: Lim, LizaAlbum: Mother TongueLabel: BR KlassikTitle: The Compass, II. – Artist: William Barton (digeridoo), Carin Levine (flute), Bavarian Radio Symphony Orchestra/Christoph PoppenComposer: Lim, LizaAlbum: Musica Viva Vol. 47Label: BR KlassikTitle: A Sutured World, IV.
