This Tuesday, December 23, Bela Fleck and Abigail Washburn will be broadcasting a live duo performance from their living room in Nashville in support of one of their favorite charities, Stand for Children.

Not only will the duo perform during the hour+ broadcast, they’ll also take questions from the live audience. Head to Concert Window at 7:30 p.m. ET on Tuesday night to tune in. You can pay what you want to access the broadcast, but keep in mind all proceeds benefit Stand For Children, a national organization that works across the country – from the classroom to the Capitol – to mobilize all Americans to make sure children are given the resources and opportunities to have a productive and satisfying future.
