I'm sure if anyones following my ranting about costumes on stage in another post, this might raise some laughs, but I was doing some last minute upgrades on what I'd be wearing on the stage, it was full on industrial noise kinda set and I wanted more circuitry coming out of me, as you do. We were young, silly, no real tools, and high, and I was trying to snap a circuit board with my hands.
I struggled for a while, then suddenly snapped and the rough edge went through two fingers. One, nasty cut but was fine, the other over the line I hold my stick, little whitish noodle shaped thing dangling out of the wound...I stopped drumming after this, its only now about 12 years later the scare tissue and feeling has returned enough that I can play drums again.
