From 1985, the beginning of their collaboration in Amsterdam, Peter Bosch and Simone Simons have been involved in performances, concerts and theatre productions. Since 1990, however, they have focused in particular on the development of autonomous music machines.

All these machines are dynamic: Sound and movement are constantly evolving. »Krachtgever« is their best-known piece for its Golden Nica, received at Prix Ars Electronica, Linz, 1998. The other projects on the LP are »Cantan un Huevo«, commissioned by the Ives Ensemble in 2000 and awarded in 2002 at the 29th edition of the International Competition of Electroacoustic Music and Sonic Art, Bourges, France, and one of their first installations, »Was der Wind zum Klingen bringt«, from 1989/90, shown in the Stedelijk Museum, Amsterdam, 1990, as part of the exhibition »Energieën«, and in 1991 at the Multimediale 2, Z.K.M., Karlsruhe. The LP demonstrates that sound produced by the Bosch & Simons music machines can also be listened to as autonomous »music«.
