Zawinul later joined Shorter in contributing to the initial fusion music recordings of Miles Davis, and both men were part of the studio groups that recorded the key Davis albums "In a Silent Way" (1969) and "Bitches Brew" (1970). Consequently, Weather Report has often been seen as a spin-off from the Miles Davis bands of the late 1960s and early 1970s, although Zawinul was never part of Davis's touring line-up. Weather Report was initially formed to explore a more impressionistic and individualistic music (or, as Zawinul put it, "away from all that eight bars shit and then you go to the bridge...").
