Cellist Yo-Yo Ma joined Diane for an interview on The Diane Rehm Show in November 2007. He had just released an album titled “New Impossibilities” with the Silkroad Ensemble, a group Ma had founded to “draw on a rich tapestry of traditions from around the world to create a new musical language that weaves together the foreign and the familiar.”

In the interview they discuss Ma’s belief in the power of music to cross borders and bridge differences. He also explains why, after more than four decades of playing the cello, he finally realized that being a musician makes him happy.

This interview is part of Diane’s special summer series in which she shares some of her favorite interviews with singers, songwriters and musicians from her archives.
