Joanna Bailie was born in London in 1973 and has been living in Brussels since 2001. Her work as a composer has been performed at festivals such as the Venice Bienale and the Huddersfield Contemporary Music Festival by ensembles such as Musikfabrik, The Nieuw Ensemble, Orkest de Volharding and the London Sinfonietta. Her music is regularly broadcast on BBC Radio 3. Since 2003 she has been the co-artistic director of Plus-Minus, an Anglo-Belgian contemporary music group.
Over the past few years she has become increasingly involved in collaborative work and in May 2006 she provided the electronic soundtrack for choreographer Brice Leroux's Quantum Quintet at the KunstenFESTIVALdesArts. Joanna Bailie has been invited by the SPOR festival in Denmark to curate the 2010 edition with a program entitled "Music+".

Christoph Ragg, born 1970 in Rheinhausen (Germany), has been resident in Brussels since 2003. After a period as assistant at the opera house in Düsseldorf he has worked as a freelance scenographer for various choreographers and directors such as Ivo van Hove, A.T. de Keersmaeker, Kirsten Debrock and Claudio Bernardo at theatres in Amsterdam, Brussels and Nice.
For three years he was the resident scenographer at "Nadine", a performing arts centre in Brussels. In 2002 he formed the collective "C&H" along with Heike Langsdorf and Christophe Meierhans. Chiefly concerned with conceptual performance, C&H's recent projects have recently been presented at the Playground festival in Leuven, the opening festival of the Centre Pompidou in Metz and the KunstenFESTIVALdesArts in Brussels.
