To complete the band, Zawinul, Shorter and Vitouš brought in former McCoy Tyner drummer Alphonse Mouzon and began recording their debut album while looking for a full-time auxiliary percussionist. The initial recruits were session percussion 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. Guitarist John McLaughlin was also invited to join the group, but decided to pursue his solo career, instead.
