NEW BERLIN – The New Berlin Art Forum will present “Not So Sharp,” a student directed a cappella group from Hartwick College, Oneonta, in concert at St. Andrew’s Episcopal Church on Saturday at 7 p.m.

They have performed in Prague and the Czech Republic while traveling with Hartwick College and as the opening act for Martin Short and “Up in the Air,” a small ensemble group from Tiffin University.
