Now living in Newfoundland, cellist Ofra Harnoy has been inspired by the immensely rich musical heritage of the island, so much so that she chose to devote her new album, “On the Rock,” to the province’s familiar and wonderful repertoire. She has invited guests such as Fergus OByrne, Alan Doyle, Amanda Cash, Bob Hallett, and Mike Herriott to join her. With her cello at the forefront, the result is a magnificently vibrant and unprecedented musical celebration of Newfoundland.
