The exhibit Working Papers presented notes, instructions and documents of early compositions for The Orchestra of Excited Strings and other projects, created in New York between 1976 and 1981. These documents offer a view to the creative process from an inside perspective. The exhibition also included a number of recent drawings related to music composition, including an original score for a specially issued signed CD Edition of 25. (see Discography). The exhibition ran from Deccember 11, 2006 until March, 2007.

'The first exhibition at my newly established gallery and record store GELBE MUSIK, opening December 11, 1981, was devoted to scores. The show offered a rather broad view to the idea of scores and musical notation. In doing so. I followed John Cage's approach of presenting different forms of musical scores in his book Notations, published in 1969.Cage's collection contains traditional scores as well as examples of "open forms", like graphic notation, verbal scores and performance instructions. A piece of string with knots, which Terry Fox had used in several of his performances, was probably one of the most uncommon scores in that first show.
