Bootleg is the first live recording that is actually made by the crowd. The art duo Ma Ma produced empty vinyl. No music. No Sound. Before concerts they put them on the floor and people danced on them. After the concerts the records were scratched. These scratches made sound on the record player. Music artist Daniel Freitag mixed this noise in the studio and created new tracks out of it.
