Béla Fleck and Abigail Washburn, “the king and queen of the banjo” (Paste), have a musical partnership like no other. Béla Fleck is a fifteen-time Grammy Award winner who has taken the instrument across multiple genres, and Abigail Washburn a singer-songwriter and clawhammer banjo player who re-radicalized the instrument by combining it with Far East culture and sounds. The two met at a square dance, began collaborating musically and eventually fell in love. Over the years, they played together most visibly in the Sparrow Quartet alongside Ben Sollee and Casey Driessen and informally at a pickin’ party here, a benefit there, or occasionally popping up in each other’s solo shows. Fans of tradition-tweaking acoustic fare eagerly anticipated that Béla & Abigail would begin making music together as a duo, and now it's happened! They'll perform pieces from their Grammy-winning self-titled debut as well as their new record, "Echo in the Valley."
