Frontier Ruckus is a bluegrass infused folk band out of Michigan. They've received a lot of local recognition from their two full length releases The Orion Song Books (2008), and Deadmalls & Nightfalls (2010), and are beginning to receive national attention as well. Their songs are full of imagery laced lyrics. Also, they have a musical saw in the band!
Here's Frontier Ruckus performing "Nerves of the Nightmind"!
Frontier Ruckus has a couple of great studio sessions you can access. Here's one from Paste, and another one from Daytrotter. Check out the band's website for more info!
