Italian singer Andrea Bocelli is a superstar. The Grammy- and Emmy-nominated tenor is one of the highest-selling vocalists in music. In 1999, Bocelli scored a Guinness World Record for simultaneously holding the No. 1, 2 and 3 spots on Billboard's Classical Top 10 chart. Since then, Bocelli has collaborated with everyone from Celine Dion to Ariana Grande. But on his latest album, Sì, Bocelli tries something he finds really daunting — recording with his 21-year-old son, Matteo.

Yo-Yo Ma opened his recent Tiny Desk concert with the gently rolling "Prelude" from J. S. Bach's Unaccompanied Cello Suite No. 1. It's music Ma has lived with nearly all of his life.

"Believe it or not, this was the very first piece of music I started on the cello when I was four years old," he told the crowd, tightly squeezed between the office furniture on NPR's fourth floor.

Icelandic composer Ólafur Arnalds was in a hotel lobby somewhere in Asia when he first saw a modern version of a player piano. This particular one was tapping out The Beatles' "Yesterday."

If you want to know how much the Bolshoi Theatre means to Russia, pull out a 100 ruble note, and there it is: the grand facade of the building.

Go inside, and it's an imperial wonderland. Gilded balconies ring the stage, and more than 100 crystal chandeliers shimmer above rows of crimson velvet seats.

It's impressive, but not quite as impressive as what's happening onstage. Dancers in toe shoes and tights are rehearsing Anna Karenina, a ballet based on the Tolstoy epic.
