When Brenau University music professor and pianist Ben Leaptrott accompanies cellist Charae Krueger and violinist Kenn Wagner at a concert Tuesday night, Feb. 5, another “performer” will debut on the stage at historic Pearce Auditorium: a brand new Steinway & Sons concert grand piano. The concert, which starts at 7:30 p.m., is free and open to the public. Brenau leased the piano to kick-start its fundraising effort to become an “All-Steinway School.”
