The Knebworth Festival was held in 1979, which was the last UK performance. Since a good sound board sound source and a high-quality audience sound source were left, a matrix sound source like this work was completed. Completely recorded on August 4th and August 11th! The matrix sound source that combines the goodness of the sound board and the goodness of the audience sound source is something that can only be realized if the two types of masters are excellent, so it is limited in Zep's live history. And the amazing master is discovered again! The one included in the bonus CD is a genuine multi-track soundboard master that is not a video drop!
