The change in approach affected the band deeply. Repetitive funk did not suit Vitouš' talents. Zawinul judged Gravatt's approach to be unsuitable for some of the new pieces he had written. Andrew White III had returned to play occasional English horn on the album, but Zawinul also employed him on bass guitar on three tracks to get the style of funk playing required. For similar reasons, the studio-based drummer/composer Herschel Dwellingham played drums on four of the album's six tracks, replacing Gravatt entirely on three of them, on "Non-Stop Home" Dwellingham and Gravatt played together, with Gravatt the sole drummer only on "125th Street Congress". Muruga Booker also contributed percussion to the sessions alongside Dom Um Romão.)
