Rice is the drummer for the technical death metal band, Job For a Cowboy (not nearly as funny as Cattle Decapitation, huh?). I sent him a 5x7 and SASE on August 4, to Revolution Hall in Troy, New York. The show was on August 13, and I received my pic signed, on the back with a long note, on August 17.
I asked him a question about his nickname, that's what he was referring to at the bottom of the note.
The return addy is the venue's, not Rice's.
