"Baritone Jason Detwiler was a suave and arrestingly musical force as Nick Carraway"

- San Francisco Chronicle

"Detwiler sings with excellent diction, seamless legato, musical intelligence & unquestionable beauty of tone; notes are attacked straight on, hurled across the footlights with commanding power."

- Opera News

"Detwiler [as Escamillo] brings a tall, compelling stage persona to the role, as well as dark, burnished, thrilling vocal texture and exciting high notes."

- Classical Sonoma
