Foghorn Stringband (official bio AMG MyS FB) are an old-timey bluegrass band from Portland, OR. They just completed a major European tour and have their whole summer planned out (including a folk fest next weekend -- if you're in the area, I'm jealous).
This is fast and furious (in a slightly different way from this take on Stag), and the speed and energy the band put into this are almost punishing -- I can't imagine any group of five people keeping this up live for an hour. This is from the band's major label debut in 2005, and their devoted network of fans have kept them touring ever since.
The main original lyrical motif in this version is that we can't find out exactly what time of day the shooting happened -- but it was rainy.
