Pianist Glenn Gould rocketed to fame in 1955 with his startling and original take on Bach's Goldberg Variations. Gould's fans were treated to a remake of Goldbergs in 1982, when he released a slower-paced rendition just before his untimely death. But it's that first, rapid fire 1955 recording that continues to captivate audiences.

Classical and folk music continue to intermingle in fascinating ways. The intersections stretch back far beyond Bach, who cleverly slipped a German folk song into his Goldberg Variations. Later, composers like Ralph Vaughan Williams and Béla Bartók combed the countryside, collecting tunes from villagers.

What does it take to be an opera superstar? Jonas Kaufmann should know. He's been called "the world's greatest tenor."

Kaufmann has the voice. He's also got the onstage charisma, the movie-star good looks, the ambition, even a little controversy — and a brand new album.

At first glance, Devonté Hynes and Philip Glass might appear like musical opposites. Hynes, the 31-year-old British producer and songwriter who performs under the name Blood Orange, makes hit records with Solange and Carly Rae Jepsen.
