Klub Feniks has been with us since 1943, and to enter its upholstered interior is to step back in time. Today it will be transformed by two sound sculptors. Releasing on Opal Tapes, Wanda Group creates slow-moving, decaying pieces driven by startling emotional power. Valerio Tricoli conjures up unsettling tension, full of surprise and anxiety, constructing surreal narratives using a live sampling device; his live shows are almost ritualistic in their intensity.
