In July 1973, during a pivotal moment in his career, Van Morrison performed at The Rainbow in London with The Caledonia Soul Orchestra. This live recording showcases his dynamic blend of soul, jazz, and rock, which had been evolving since the critical success of his 1970 album, *Moondance*. Leading up to this concert, Morrison had released *Saint Dominic's Preview* in 1972, which featured hits like "Jackie Wilson Said (I'm in Heaven)" and solidified his status as a prominent figure in the music industry. The Rainbow concert not only highlighted his prowess as a live performer but also his innovative approach to blending musical styles, with a talented ensemble backing him, including notable musicians like Jeff Labes on piano and organ and John Platania on guitar. The high-energy atmosphere of this performance captured the essence of Morrison's artistic evolution during this vibrant period of his career.
