“La voix, au timbre centré un brin nasal, conserve son homogenité intelligement les phrase pour offrir un chant soigné, d’une diction precise…” - Olyrix
“John Irvin comes out of the difficulties [of faust] with honors and delivers a lovely duet with marguerite, succeeding even with agility his passage to the c sharp in “ange adoreé”. in short, he has the intelligence of the rossinians, and shows himself to be a good connoisseur of french style” - Christine ducq
“Among the soloists, John Irvin’s Faust - impressively, a late replacement - offered polished French diction, a refined tone and, crucially, a persuasive micro-climate of melancholy that, until he encounters Marguerite, darkens his every thought of pleasure. Irvin’s high lying silvered tenor blended authority and anguish, never merely serene when he lusciously hymns “Nature Immense”, but growing in force and scope as his beloved offers him both reason to live - and, saving her, to die and to be damned.” - The Arts Desk
