Just saw him yesterday at Hardly Strictly Bluegrass in San Francisco and holy crap, this guy is a genuine badass. I saw him a couple of years ago and he wasn't this..yet.
Now he and his band have grown into one fine band. Swamp rock mostly, not much country at all.
You can watch the show live from most stages or the rest of the festival, or any show from the festival on the hsb app.
