Dear Editor:The Ukrainian Bandurist Chorus of North America was an amazingly special treat for me on March 17 at the Cleveland Museum of Art. Under the able leadership of the chorus’s gifted artistic director/conductor, Maestro Oleh Mahlay, the concert was one in a series given by this talented ensemble of almost 60 singers and bandurists during its centennial year, continuing a tradition dating back to the Kobzar Choir of 1918. Having just completed a triumphant tour of Ukraine, the ensemble is on a U.S. tour, which included concerts in Chicago and Cleveland, and continuing on to eight other cities.
