In March 1970, Davis began to perform as the opening act for rock acts, allowing Columbia to market "Bitches Brew" to a larger audience. He shared a Fillmore East bill with the Steve Miller Band and Neil Young with Crazy Horse on March 6 and 7. Biographer Paul Tingen wrote, "Miles' newcomer status in this environment" led to "mixed audience reactions, often having to play for dramatically reduced fees, and enduring the 'sell-out' accusations from the jazz world", as well as being "attacked by sections of the black press for supposedly genuflecting to white culture". The 1970 tours included the 1970 Isle of Wight Festival on August 29 when he performed to an estimated 600,000 people, the largest of his career. Plans to record with Hendrix ended after the guitarist's death; his funeral was the last that Davis attended. Several live albums with a transitional sextet/septet including Corea, DeJohnette, Holland, Moreira, saxophonist Steve Grossman, and keyboardist Keith Jarrett were recorded during this period, including "Miles Davis at Fillmore" (1970) and "" (1973).
