American indie rock band Broken Bells will donate $1 from every ticket sold for their upcoming tour to help protect its fans from asteroids. The band is looking to accomplish this by working together with the B612 Foundation, a non-profit organization dedicated to that exact purpose. Anyone who buys a ticket to the April 15th after-party can expect to see not only Broken Bells but also foundation notables like Dr. Marc Buie, the mission specialist on the Sentinel project, and Rusty Schweickart, Apollo 9 astronaut and cofounder of B612.
