Imagine an experimental band made entirely of machines—not the animatronic kind that haunts your childhood memories from bad birthdays at Chuck E. Cheese, but something that looks like it came from the basement of a mad scientist. The sculptures in Neil Feather's exhibition are each exquisite, and nearly ecstatic, contraptions involving multiple moving parts. But each of them is also part of a larger machine that takes over not only Feather's gallery at the Walters, but, when the volume is right, as it was on a recent visit, the entire museum. 'The Anaplumb,' a crazy, weighted string instrument, was turned up "too loud" according to the Walters' guards, so that it created a Sonic Youth-y screech loud enough to wake the mummies up on the second floor. It was fucking rad. The piece is comprised of string that hangs from a dozen feet up near the ceiling with a small, duckpin-size ball on the bottom. The ball is, evidently, moved by magnets, causing the string to vibrate into guitar pickups. The only problem when the volume was turned up to 11 was that, like a guitar player who is turned up louder than the band, it drowned out the other instruments. Later in the day, it was a bit quieter and everything was working brilliantly together.
