Last night's fairly majestic Neil Young & Crazy Horse gig finished up with Like A Hurricane. Frank Sampedro was torturing a keyboard/synth which descended on wires from the lighting gantry and swayed from side to side as he throttled it to within an inch of its life. Neil Young followed the descent into cacophony by taking his keys out of his pocket and proceeding to saw through all six strings at the body end so they hung from the headstock. He then grabbed the strings and rubbed them over the pickups to make further tortured squalls of noise until the song lumbered to a close and the gig was over. I wasn't all that impressed that such an epic song plunged into several aimless minutes of random noise rather than going out on a powerchord or two.
What's the worst treatment of an instrument of pleasure you've witnessed at a gig?
