Bummer, I was supposed to see him with Jason Isbell this spring.
There are not many folks who originate a sound. Merle did.
I love the story about Merle meeting Johnny Cash, and telling Johnny how much he enjoyed being at the San Quentin show. Johnny asked, "were you a guard there?" "No," Merle replied -- "I was an inmate." (he was there on a robbery charge IIRC).
What a bad year for my musical icons so far. Bob Dylan, go drink some OJ or something.
