The band's performance at Woodstock and the follow-up sound track and movie introduced them to an international audience and garnered critical acclaim. The sudden success which followed put pressure on the group, highlighting the different musical directions Rolie and Santana were starting to go. Rolie, along with some of the other band members, wanted to emphasize a basic hard rock sound which had been a key component in establishing the band from the start. Santana, however, was increasingly interested in moving beyond his love of blues and rock and wanted more jazzy, ethereal elements in the music. He became fascinated with Gábor Szabó, Miles Davis, Pharoah Sanders, and John Coltrane, as well as developing a growing interest in spirituality. At the same time, Chepito Areas was stricken with a near-fatal brain hemorrhage, and Santana hoped to continue by finding a temporary replacement (first Willie Bobo, then Coke Escovedo), while others in the band, especially Michael Carabello, felt it was wrong to perform publicly without Areas. Cliques formed, and the band started to disintegrate.
