In Review: Andreassen gives "powerful performance" in Nashville Opera "Susannah"
"A powerful performance was given by bass-baritone Gustav Andreassen, as Olin Blitch. The ominous, black water of his voice washed over the audience and at times its dominance was poignantly arresting. While intense, Andreassen's voice remained smooth and controlled, even paired with the sometimes-angular score. A testament to his dramatic prowess, the audience hated Blitch in the best way."
