At this point, Vitouš and Zawinul found themselves at creative loggerheads, since the former preferred Weather Report's original approach and the latter wished to continue further along the road to funk. Retrospectively, Zawinul accused Vitouš of being unable to play funk convincingly (something which Greg Errico corroborated) and claimed that he had not provided enough music for the band. Vitouš countered that he had in fact brought in compositions, but that Zawinul had been unable to play them. Vitouš has also accused Zawinul of having been "a first-class manipulator" primarily interested in commercial success. When Shorter sided with Zawinul, the original three-man partnership broke down acrimoniously and Vitouš left Weather Report, moving on to an illustrious career leading his own band and winning respect as a composer. His final contribution to Weather Report was to play bass on a single track, which appeared on the band's 1974 album "Mysterious Traveller" ("American Tango", which he had co-written with Zawinul).
