Master cellist Bernard Greenhouse, 92, and his 300-year-old Stradivarius cello have been constant companions for the last half century.
Greenhouse was a founding member of the legendary Beaux Arts Trio, which plays its final U.S. concert at the Tanglewood Festival in Massachusetts.
Make sure to take the time to listen to it all. A superb example of what a real musician is, and what a sense of calling means.
