Carlos Augusto Alves Santana (born July 20, 1947) is a Mexican-born American Grammy Award-winning rock musician and guitarist. Santana became famous in the late 1960s and early 1970s with his band, Santana, which pioneered a blend of rock, salsa and jazz fusion. The band's sound featured his melodic, blues-based guitar lines set against Latin percussion such as timbales and congas. Santana continued to work in these forms over the following decades. He experienced a sudden resurgence of popularity and critical acclaim in the late 1990s. Rolling Stone also named Santana number 15 on their list of the 100 Greatest Guitarists of All Time in 2003.

Santana was born in Autlán de Navarro, Jalisco, Mexico. His father was a mariachi violinist, and Carlos learned to play the violin at age five and the guitar at age eight. Young Carlos was heavily influenced by Ritchie Valens at a time when there were very few Latinos in American rock and pop music. The family moved from Autlán de Navarro to Tijuana, the border city between Mexico and California, and then San Francisco. Carlos stayed in Tijuana but joined his family in San Francisco later and graduated from James Lick Middle School and Mission High School there. He graduated from Mission High in 1965.

In San Francisco, the young guitarist got the chance to see his idols, most notably B.B. King, perform live. He was also introduced to a variety of new musical influences, including jazz, world music, and folk music, and witnessed the growing hippie movement centered in San Francisco in the 1960s. After several years spent working as a dishwasher in a diner and busking for spare change on the streets, Santana decided to become a full-time musician; in 1966, he formed the Santana Blues Band, with fellow street musicians David Brown and Gregg Rolie (bassist and keyboard player, respectively).
