Virtuoso mandolin player and ethereal tone-true vocalist Sierra Hull publically entered the bluegrass world as a teen prodigy on the Grand Ole Opry stage with Grammy-winning artist Alison Krauss. Her newest album (produced by Bèla Fleck) introduces Sierra as a composer and lyricist with a genre-transcending soundscape claiming bluegrass at its roots, but finding its wings in original music that rings with both harmony and dissonance. 8:00 p.m. Early Bird through 8/17: $20. Regular: $25
