Viva Vivaldi, the Ars Nova Musicians' annual Baroque homage, is ending its 39th season with some serious off-roading -- a performance of Rachmaninoff's Second Piano Concerto. The soloist is Nichols grad and Boston College student Alexander Aylward. Last year for Viva Vivaldi, Aylward played Beethoven's "Emperor" Concerto and brought the house down. This year, he joins the Ars Nova and Marylouise Nanna in concert at 6:30 p.m. Nov. 19 at St. Michael's Church (651 Washington St.). A $12 donation is requested.
