While searching for something else to dedicate his time to, Anthony auditioned for Sing, which he thought was a talent show. "In junior high school, I had this singing group called The Halsey Trio. We would sing songs by The Temptations at school assemblies, so I figured I could do something like that again," Anthony explained. "As it turns out, I auditioned for a musical by accident and they gave me the lead. I wasn't sure I could do it, because it was a big time commitment. But I did the musical and I loved it and decided to do more."
Since then, Anthony has had roles in Hamilton, Will & Grace, A Star Is Born, Godzilla: King of the Monsters, and of course, In the Heights.
