The Tinguely Museum in Basel is not only a museum but also a prime venue for concerts and live performances. Over the past several months a panorama of various Swiss artists were guests at the museum and brought a performance art concept to live which was called PerformanceProcess, a collaborative project by Museum Tinguely, Kaserne Basel, Kunsthalle Basel, in partnership with Centre culturel suisse, Paris. On the 26th of January, as part of a two-day international symposium, performance artist Christian Marclay took up the challenge to interact with the artwork of Jean Tinguely. Joined by Okkyung Lee (Cello) and Luc Müller (Percussions), the trio performed an amazing concert in the midst of machines created by Jean Tinguely and other material found in the museum by interacting with them spatially and by the sounds they produce; joining carefully selected random analog noises with sounds played by instruments into a coherent, Free-Jazz-like soundscape.
