Weather Report was one of the first jazz fusion groups, and one of the most influential.
He was trained in New York in 1971 by keyboardist Joe Zawinul and saxophonist Wayne Shorter, as well as bassist and contrabassist Miroslav Vitouš. Both had already been part of trainings with Miles Davis. Wayne Shorter first, in the legendary quintet of the 1960s (with Herbie Hancock, Ron Carter and Tony Williams). The influence of the Miles Davis electric period is quite blatant with open atmospheres where there are long ranges of improvisations without theme. The beginnings of these atmospheres between Zawinul and Vitous are omnipresent a year earlier in Miroslav's Purple album, with Billy Cobham and John McLaughlin.
Shorter and Zawinul remained the main members of the group, while other musicians followed each other.
