A collaboration with John Coltrane's widow, Alice Coltrane, "Illuminations" (1974), followed. The album delved into avant-garde esoteric free jazz, Eastern Indian and classical influences with other ex-Miles Davis sidemen Jack DeJohnette and Dave Holland. Soon after, Santana replaced his band members again. This time Kermode, Thomas and Rauch departed from the group and were replaced by vocalist Leon Patillo (later a successful Contemporary Christian artist) and returning bassist David Brown. He also recruited soprano saxophonist, Jules Broussard for the lineup. The band recorded one studio album "Borboletta", which was released in 1974. Drummer Leon "Ndugu" Chancler later joined the band as a replacement for Michael Shrieve, who left to pursue a solo career.
