The Semiconductor showed both sides. It started out butch, its walls glassy black; during the concert it went in gaudy drag as the sound-sensitive walls reacted to the music with color streaking, wavelengthing in oscilloscope patterns, shades of blue-white for high end, red and purple for bass and percussion, reacting vividly, hypnotically to each note. The minimonos disliked reactive walls. They called it kitschy.
