The Grammy In Mathematics
An anonymous reader writes "A mathematician will receive a Grammy award for restoring the only known recording of a live Woody Guthrie performance — a bootleg someone made in 1949 using a wire recorder. Guthrie's daughter, who had never heard her father perform in front of a live audience, oversaw the restoration. The article links very cool before and after clips."
The title of the article says the mathematician was norminated for a grammy, yet the article itself says the recording was put forward, which sounds more plausible.
It's poorly phrased, but they mean the only known live recording of *that* performance.
