On stage, Allan has enjoyed critical praise for his Lysander/A Midsummer Night's Dream for English National Opera, Benedict in Opera Comique’s production of Béatrice et Bénédict, for his Ferrando/Cosi fan tutte and his Camille in Opera North’s production of The Merry Widow.

Recent concert engagements have included Carmina Burana with the BBC National Orchestra of Wales, his well-received debut with the New York Philharmonic in performances of Mendelssohn’s Elijah, Handel’s Messiah with the Boston Handel and Haydn Society, and playing Cassio in a concert performance of Verdi’s Otello with the London Symphony Orchestra which has subsequently been released on the LSO Live label.

His recordings include Handel’s Messiah for EMI, recorded live from King’s College Cambridge and released as a DVD, and a live recording of Handel’s Joshua for the London Handel Society.
