However, the album was recorded during yet another period of change for the group, with multiple personnel shuffles. Although Alyrio Lima played percussion on one track, he was replaced during the sessions by Don Alias (his first appearance with the group since the debut album debacle) and by Alex Acuña (a Peruvian drummer and conga player based in Las Vegas, who had played with Elvis Presley and Ike Turner, among others). Alphonso Johnson was also worn out from the strain put on the rhythm by the band's frequent changes of drummer. During a break in activity halfway through the recording of "Black Market", Johnson opted to leave Weather Report to play with the Billy Cobham/George Duke Band (which featured a young John Scofield on guitar).
