Yo-Yo Ma

Since it was founded by cellist Yo-Yo Ma 16 years ago, the Silk Road Ensemble — an artistic collective comprised of master musicians and other artists from more than 20 countries, spanning the globe — has become an incubator for inspiring cross-cultural collaborations.

When it comes to artistic partnerships, there's a lot to be said for the fireworks of musicians joining together for the first time. But there's another kind of collaboration that can yield profound pleasure: a recording with two artists who know each other deeply, in a relationship that has unfolded over years or even decades.
