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 and American percussionists Don Alias and Barbara Burton. The band was initially co-led by Zawinul and Shorter but as the 1970s progressed, Zawinul became the primary composer and creative director of the group. Other prominent members throughout the band's history included bassists Jaco Pastorius, Alphonso Johnson and Victor Bailey, drummers Chester Thompson, Peter Erskine and Omar Hakim, and percussionists Airto Moreira and Alex Acuña. A quintet of Zawinul and Shorter plus a bassist, a drummer, and a percussionist was the standard formation for Weather Report.
