Teenage San Francisco Bay Area guitar prodigy Neal Schon joined the Santana band in 1971, in time to complete the third album, "Santana III". The band now boasted a powerful dual-lead-guitar act that gave the album a tougher sound. The sound of the band was also helped by the return of a recuperated Chepito Areas and the assistance of Coke Escovedo in the percussion section. Enhancing the band's sound further was the support of popular Bay Area group Tower of Power's horn section, Luis Gasca of Malo, and other session musicians which added to both percussion and vocals, injecting more energy to the proceedings. "Santana III" was another success, reaching #1 on the album charts, selling two million copies, and yielding the hit "No One to Depend On".
