Cable Car Music Rolf Langebartels performs concerts of site specific and improvised music in the installation CableCar Music., i.e. solo concerts and concerts together with other musicians, who play Cable Car Music as well or other instruments like guitar or percussion. Slide projections and videos sometimes complete a concert to a kind of music theater. "But finally there were a few high lights: Rolf Langebartels improvised on a mechanical electronic cable car installation a meditative but unusually exciting music suite using cables, jerrycans and effect devices."
