An art exhibition by former Urban Verbs guitarist Robin Rose features a circle of guitar FX pedals stuck to a wall, and a Fender Stratocaster stuck to a ceiling.
"Ascendant (below, starting top-right) captures the skyward joy that comes when you catch a good groove. Gearheads (that's us, presumably), from top to bottom: that's a 1965 Fender Stratocaster with reverse tremolo, gold guitar cable, Marshall 800 Lead Amp Head, 1960 Slant speaker cabinet."
"Isolation, the circular work on the left, is assembled from 50 guitar effect pedals, with interconnecting cables… each pedal is an independent entity (in reality, and metaphorically), and each is connected to its peers, but through a loop that never accepts external input or offers external output."
"So, we can use this to consider the social world, where social circuits can also loop closed and cut off outside contact."
Scott Matthews has a few more details on the Electro-Harmonix blog (he digs the Big Muff Pi at bottom-centre, of course) and makes one vital observation: "I first imagine myself standing in the middle of a dream pedalboard, but then I realize they're all turned away from me."
