 Live performance has always played an important part in Kraftwerk's activities.Also, despite its live shows generally being based around formal songs and compositions, live improvisation often plays a noticeable role in its performances.This trait can be traced back to the group's roots in the first experimental Krautrock scene of the late 1960s, but, significantly, it has continued to be a part of its playing even as it makes ever greater use of digital and computer-controlled sequencing in its performances.
