The Toilet, the Clitar, Tomicon and Motorguitar are just a few of the homemade functional art pieces the Heavils strum in the studio and onstage. Ax-grinder Brian Carter created these ultrabizarre-shaped guitar-bass hybrids, using the instruments’ unique sonic capabilities to concoct a sound that’s equally eccentric. Fist-poundingly heavy but still as musically twisted as old-school Zappa, this is not your average garage band — unless your garage happens to be located somewhere near the outer rings of Jupiter. The quartet has been together only a short while, but its live shows are already causing an underground stir from the Midwest to Canada. Bring some earplugs (and a few rolls of Charmin) — the Heavilution has begun.
