From Pittsburgh Opera's Tosca:
"In Pittsburgh Opera's production of Tosca, Greer Grimsley brings to the villain's role such a multifaceted performance that the Opera might as well change the billboards to read 'Scarpia!'"From Vancouver Opera's Macbeth:
"Greer Grimsley, as Macbeth, is nothing short of uniformly perfect. As someone who had yet to be awed by a bass-baritone, Grimsley will forever be my first. The power of his voice is such that the audience can literally feel his crecendos in their chests and the shaking of the floor in his lower register. His international reputation as a first-class singer and actor is well earned."
-Steven Schelling
"...the glory of his Macbeth is in the rich, robust voice and vital presence."
-David Gordon Duke
