In February 1970, during the performance of “Witch's Promise” at the Beat Club in Bremen, Jethro Tull was on the brink of significant success. This live recording occurred shortly after the release of their critically acclaimed album "Benefit," which came out in 1970, and was one of the band's early forays into blending rock with progressive elements. The song "Witch’s Promise" was a non-LP single that showcased Ian Anderson's distinctive flute work and lyrical storytelling. It was an important period for the band as they were transitioning from their earlier blues and folk influences to a more intricate sound that would define their future works. The choice of performing this song live emphasizes their innovative approach to music and composition during this pivotal time in their career.
