's experimentation and willingness to take unprecedented risks touched every aspect of their music. The Krautrock legends' innovative approach to studio albums produced some of the most exciting results of the entire era of rock music they existed in, but the foundation for their studio brilliance was in their otherworldly powers as a live entity. captures some of this live magic, documenting the entirety of a 90-minute-long, fully improvised concert made up of five lengthy jams.
