I had a chance to go see them last night at a small venue here in Fort Collins, it was excellent!
If you like Bluegrass / Rock, I suggest checking them out. My friends have been talking about them for a while, but this was the first time I was in town when they were here.
The bass player's bass is made of an old gas tank, and is single stringed. Watching him play is a trip.
A local band named Oakhurst opened, and they were good as well. The mandolin player was awesome.
