Biography

American baritone Robert Mellon is widely recognized for his "immense skill as an actor" and a "glorious voice that burst out brimming with life and vigor." Praised by Opera Today as a theatrical "force field" with a "rolling baritone caressing legato passages with poise and sheen," Mellon brings a commanding, electrifying energy to the stage. Opera News commended his "domineering baritone, gleaming like polished copper," while the San Francisco Chronicle praised his "rich-hued and expressively complex" portrayals that lend a profound, lasting moral weight to his dramatically charged performances.
