The 12th season of Cranberry Coast Concerts will come to a close this month with four performances set to take place in Wareham and surrounding towns.

The series founders, husband and wife Kirk Whipple and Marilyn Morales, will showcase a broad range of selections from their repertoire of classical, contemporary and original works. They will perform pieces for one piano/four hands in Wareham, Attleboro and Foxborough.

In Wrentham, they will present a program of works for two pianos. Also on the program will be surprise guests from this summer’s concert season. Whipple and Morales have toured the world together for over a quarter of a century, performing in a variety of ensembles and concert settings.
