The Texas musician was set to appear at Pleasure Island Seafood & Blues Festival on Sunday when he took ill. He worked with longtime musical partner Bnois King for almost 30 years and he is survived by his wife Phyllis.

Edward Chmelewski, president of Kubek's label Blind Pig Records, says: "Joe was truly one of the good guys, a humble, kind person and an immensely gifted musician. It's a great loss for all of us. We feel privileged to have known him and documented his music."
