If Chucky the homicidal doll had gotten a scholarship to Juilliard and developed an obsession with John Cage instead of murder, he might have been the first circuit bender. An international movement attracting musicians, artists, performers, noiseniks and mad scientists, circuit bending typically involves the manipulation of simple electronics — especially those found in children's toys like talking dolls — into avenues of sonic expression that Playskool just wouldn't understand. This year's Bent Festival is LA's fifth and most ambitious to date, with concerts by celebrity benders from all over the world, plus workshops, demonstrations, and parties over three days at two downtown locations.
