One of the most charming stories I've heard on This American Life.
Act One. Dewey Decibel System. Alex Blumberg tells the story of an audacious act of rebranding done by a group of people who aren't normally thought of as very audacious: public librarians. In Michigan, they've started staging rock concerts in libraries. The band that's been thrown into the experiment – The High Strung – couldn't be more perfect for the job. (22 minutes)
