When Holland & Knight partner Robert Highsmith isn’t manning his practice or exploring underwater caves, he’s singing and playing guitar in some of Atlanta’s smaller music venues. On Friday, he’ll take his talents to a slightly bigger stage, Phillips Arena, as he opens Game 3 of the Eastern Conference NBA Semi-Final game between the Atlanta Hawks and Cleveland Cavaliers by singing the national anthem.

“I’m really excited,” said Highsmith, his grin virtually visible over the phone.
