Happy Pi (or Pie) Day! Today has taken on a special meaning for math heads and people who just like to eat pie. If you're looking for a little bit of background, Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter "e") is the symbol used in mathematics to represent a constant -- the ratio of the circumference of a circle to its diameter -- which is approximately 3.14159. As for Pie Day, don't think about it too hard and just grab a slice of pie to celebrate.

For our 9:30 Coffee Break today we'll celebrate both. We're looking for songs about circles or pie.

Are you a fan of Blitzen Trapper? You can win a private show from the band and a visit from Jill and Steve if you tell them why you deserve a Coffee Break on the Road at: CoffeeBreak@TheCurrent.org. They'll visit you on March 28 with the band and goodies from JJ's Coffee and Wine Bistro.
