Enclosed at the back of the sheet music edition of the composition “To Lose Is To Have” is an accompanying CD without whicht the work cannot be performed. The sounds on the CD are taken from the art installation “Horchrohre” (“Listening Pipes”, 1999) by Edmund Kieselbach and were compositionally treated by the composer and Juergen Rummel. The bell sounds originate from authentic bells from pre-Christian China.
