Continuing in our list of Bluesfest finds, from two years ago, I give you Les Claypool. Super weird, totally mesmerizing, and fucking talented, he plays the Bass like nobody's business and I only went because a friend told me to and then fell hopelessly and utterly in love. Bonus, if you like him, he's done a LOT and is even from Primus! (which alas I missed at the Bluesfest THREE years ago. Didn't know I wanted to go.)
