Three splendid compositions set the stage for an afternoon of great music at 3 p.m. on Sunday, Oct. 6, at William and Helen Richards Theatre at Orange Hall, located at the corner of Wawayanda and Grandview Avenues on the SUNY Orange campus in Middletown. Cellist Wolfram Koessel and pianist Vadim Serebryany are friends who play often together as two of the three members of Trio Ink. They chose three cello and piano sonatas in which the two instruments carry equal or similar weight. General admission is $15; senior citizens, faculty, staff, and alumni pay $10. It's free for all students. For more information call 341-4891.
