By the release of Amigos, the Santana band's seventh album, only Carlos Santana and David Brown remained from the band that conquered Woodstock, and only Carlos had been in the band continuously since. Meanwhile, the group had made some effort to arrest its commercial slide, hiring an outside producer, David Rubinson, and taking a tighter, more up-tempo, and more vocal approach to its music. The overt jazz influences were replaced by strains of R&B/funk and Mexican folk music. The result was an album more dynamic than any since Santana III in 1971. "Let It Shine" (number 77), an R&B-tinged tune, became the group's first chart single in four years, and the album returned Santana to Top Ten status.
