Weather Report was an American jazz fusion band of the 1970s and early 1980s. The band was initially co-led by the Austrian-born keyboard player Joe Zawinul, the American saxophonist Wayne Shorter and Czech bassist Miroslav Vitous. Due to creative and financial disagreements, Vitous left the band after a few years. Zawinul took increasing control and steered the band towards a more funk, R&B oriented sound.

Joe Zawinul and Wayne Shorter had first met and become friends in 1959 while they were playing in Maynard Ferguson's Big Band. Zawinul went on to play with Cannonball Adderley's group in the 1960s, while Shorter joined Art Blakey's Jazz Messengers and then, in 1964, Miles Davis' second great quintet. During this decade, both men made names for themselves as being among the best composers in jazz.  Zawinul later joined Shorter in contributing to the initial fusion music recordings of Miles Davis, and both men were part of the studio groups, which recorded the key Davis albums In a Silent Way (1969) and Bitches Brew (1970). In consequence, 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...")  Zawinul and Shorter recruited another Miles Davis associate, the classically trained Czech-born bass player Miroslav Vitous, who had previously played with Zawinul, as well as with Herbie Mann, Bob Brookmeyer, Stan Getz, and Chick Corea (Vitous has subsequently claimed that in fact Shorter and he had founded Weather Report, with Shorter bringing in Zawinul afterwards.) All three men composed, and formed the core of the project. To complete the band, the trio brought in former McCoy Tyner drummer Alphonse Mouzon and set about looking for a full-time auxiliary percussionist as they began to record their debut album. The initial recruits were session player Don Alias and symphony orchestra percussionist Barbara Burton. During recording, Alias quarreled with Zawinul (allegedly due to Zawinul being too dictatorial over the percussion approach) and the innovative Brazilian percussionist Airto Moreira (yet another Davis alumnus) was brought in to complete the record. John McLaughlin was also invited to join the group, but decided to pursue his solo career, instead.
