Among the soloists in this work, Thomsen was the standout for his authoritative interpretation." Bach's Magnificat — Houston Chronicle

Thomsen quickly showed that he is the real thing...His superb, evenly-supported voice easily filled the house; he had it under total control from pp to the loudest ringing forte. His near-baritone quality provided great vocal heft...

"Pinkerton is an ideal role of tenor Mark Thomsen, and with his well-schooled vocalism and fine musicality he took the singing honors of the evening." — Opera

"Mark Thomsen was a take-charge Don Ottavio, not at all subservient to his lady. He was given some particularly tough stage directions, like hauling the dead Commendatore up a steep hill and singing 'Dalla sua pace' flat on his back. Thomsen's tenor is smoothly lyrical but substantial, with a stunning pianissimo, and his breath control in 'Il mio tesoro' was nothing short of remarkable." — Andante

"Don Jose does get to kill her... And he gets to sing, beautifully, in Thomsen's case, particularly in Act II's Flower Song"
