Shadowgrass plays Saturday, April 10. Progressive bluegrass outfit from the Blue Ridge Mountains area, formed in 2014 by guys who've been playing together since they were kids. They've put out two studio albums and tour pretty regularly around the country. The Orange Peel's sound system hits hard in a room designed to handle serious volume, so expect clean power whether you're up front or in the back. It's a standing-only floor with about 950 capacity, which means the energy stays concentrated and the acoustics work in your favor all night.
