Weather Report was an American jazz fusion band active from 1970 to 1986. The band was founded in 1970 by Austrian keyboardist Joe Zawinul, American saxophonist Wayne Shorter, Czech bassist Miroslav Vitouš, American drummer Alphonse Mouzon as well as American percussionists Don Alias and Barbara Burton. The band was initially co-led by co-frontmen Zawinul and Shorter but, subsequently as the 1970s progressed, Zawinul largely became the sole musical leader of the group. Other prominent members at various points in the band's lifespan included Jaco Pastorius, Alphonso Johnson, Victor Bailey, Chester Thompson, Peter Erskine, Airto Moreira, and Alex Acuña. Throughout most of its existence, the band was a quintet consisting of Zawinul, Shorter, a bass guitarist, a drummer, and a percussionist.
