You've probably heard of Taj Mahal and Ry Cooder- two veteran performers with a healthy respect for musical traditions of all sorts. They've charted their own paths in the world of music: outside the usual bounds of genre, and without regard to the demands of the recording industry. In the process they each created a rich, diverse body of work. UNH at Manchester English professor Fred Metting has written a book about the two performers called "The Unbroken Circle".
