1970 was a turning point for Miles Davis, and it proved to be the most consistently intriguing year of his decades-long career. Davis had previously performed exclusively in jazz clubs and festivals, and Dave Holland, when he arrived from England in 1968, noted that he was "shocked at how few people were coming to Miles's concerts." But by the beginning of 1970, in conjunction with the April release of Bitches Brew, Davis began appearing at rock venues, sharing the bill with established rockers like Steve Miller, Grateful Dead, and Neil Young and often playing to audiences of thousands. His appearance at Bill Graham's Fillmore West on October 15, 1970, highlights the transitional phase in Davis's career, with his septet following a relatively consistent set list in order to provide a cross-section of his repertoire to a young and relatively unfamiliar audience. In hindsight, this was an important move, and an acknowledgement of the reality that this was the demographic Davis would need to capture if he were to remain both fresh and relevant. This performance was rapturously applauded by a fresh audience, fully endorsing Davis's profound ability.
