Tin Brother Quartet had a terrific event.. They played the opening at Red Rocks for the Grammy award winning rock group, OneRepublic. (One Republic has had several hits but the best known might be “Counting Stars’). There were about 7,000 in the audience at Red Rocks. Tin Brother played as everyone came into the amphitheater. It was quite an honor to be selected. Masterful Musicians is so proud of this ensemble!
