For Bootleg Bureau B produced specially-manufactured blank silent vinyl records (without any music or sound). in order to capture the energy of the crowd, they taped these records to the floor of the venue during an Automat concert at Kunsthalle Dusseldorf. The crowd danced on the records and the vinyl was scratched and dirty after the show. Played on turntables you only heard noise. Automat and Schneider TM then used the noise to compose three unique tracks, presented on limited 12" collector's vinyl. Thanks to a stencil technique, footprints and dirt become the printing color which made the artwork for the vinyl.
