My coworker just went to see Tool last night. She told me at the merchandise booth, they had signed drumheads for $1600. I'm thinking - "that's ridiculous, who would pay that for a set of signed heads?" She then told me that was for EACH of the big ones (bass drums), and the tom heads were $600 each!!! I suppose something is ultimately worth whatever someone will pay for it, but that's just crazy. Thoughts?
