"Countertenor Benjamin Williamson sang “Erbarme Dich” with heart-stopping beauty and intensity, with exquisitely controlled vibrato and shading." (Bachtrack)
"His is the loveliest counter-tenor voice I have heard, and he acted this complex role with a subtlety and conviction which brought the opera to vivid dramatic life." (The Spectator)
"His Oberon is focused, attentive, and responsive, displaying deeply committed, high-stakes emotion that is always on the verge of something significant in combination with a seemingly contradictory combination of virility, sensitivity, and arrogance. If that’s not Oberon, I don’t know what is."(Washington Post)
"Benjamin Williamson’s Tolomeo is no one-dimensional villain but a convincingly querulous boy-King, indiscrete and injudicious, perpetually frustrated in his attempts to assert his power and fulfil his sexual desires. Williamson’s keenly focused, bright-edged countertenor captured Tolomeo’s petulance while the sweetness of tone hinted at finer qualities and emotions struggling to break through the yoke of immaturity. (Opera Today)
"His rendition of Music for a While blew the audience away."
