He has taken major roles in conductor Richard Hickox's semi-staged performances of opera, including Britten's Gloriana (Aldeburgh, 2003), Walton's Troilus and Cressida and most of the Vaughan Williams operas.  Other concert performances include Henze, Strauss, Stravinsky and Wagner (Donner in Das Rheingold for ENO).

He is an accomplished recital artist who can be heard at Wigmore Hall, at many festivals, and on Radio 3, where he has appeared on Iain Burnside's 'Voices' programme.  His numerous recordings include Vaughan Williams, Berkeley and Britten operas for Chandos, and an extensive repertoire of English song with pianist Iain Burnside for Naxos.
