There are no guitar players who sound like Keller and I've always been curious to understand how he gets the sound he gets. This video is a bit old but sounds like a soundboard recording. The fact it's dated is probably good, as I feel like this was when Keller was in his heyday. I saw him in the summer of 2019 at Salmonfest in Alaska for the first time since around 2003 and was disappointed how he'd taken his avant garde style to a perplexing extreme. He utterly lost the crowd. Anyway, he's an interesting and unique picker that would make for a great reaction vid.
