Traffic, the British rock band formed in 1967, was known for its unique blend of rock, jazz, and folk influences. The live recording in question comes during a significant phase in their career. Before the live performance, they released their landmark album "John Barleycorn Must Die" in 1970, which showcased the band's evolving sound and featured their experimental approach to music. The album received critical acclaim and is often regarded as one of their best works, reinforcing their status in the progressive rock scene. The timing of the live recording can be placed in the early 1970s when the band was gaining popularity and further developing their improvisational skills in live settings. Notably, Traffic was also part of the evolution of rock music into more complex forms, embracing extended jams and intricate musicianship, which would have been evident in their live performances during this period.
