What the world needs now is another cat video. Seriously.

Today our colleague Robert Siegel is retiring after four decades at NPR. He's covered everything from peace movements in East and West Germany to the Republican revolution of the 104th Congress, the mentally ill homeless and the 2008 earthquake in Sichuan Province, China.

Over his 30-year tenure as host of All Things Considered, Robert has also chased one of his lifelong passions — classical music. He's interviewed dozens of today's most compelling musicians.

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.
