Sigalit Landau performed Bauchaus 04 at the 2004 Armory Show in New York City. The piece was first performed in 2000, in Exeter, UK and in Heidelberg, Germany. The 2004 version involved the transformation of a truck-mounted concrete mixer into a large traveing, chiming, music box. This transformed mixer was both an ice cream van and a story vehicle. Several tunes and sounds were composed for the repertoire of this mixer by musicians Arik Hayut, Guy Kark, Daniel Landau, Robert Bentley, and Ohad Fishof. These melodies were played electronically and were made to sound similar to ice cream trucks. Playing music while traveling along small roads and parking at various stops, Landau distributed ice pops in the shape of the Little Matchstick Girl to participants.
