It goes without saying that a musical lineage like Salvador Santana’s doesn’t hurt in jumpstarting a career. The son of Grammy-winning (ten to be exact) Carlos Santana, the young musician also has a poet for a mother and a blues icon for a grandfather. Add his paternal grandfather (a legendary violinist and, apparently, a mariachi bandleader) to the mix, and it’s no surprise that Santana took to the family business. Staying true to the varied and diverse musical disciplines within his family, Santana opted to dedicate his talents to the keyboard, having studied piano from the age of five and attending music schools along the California coast. His San Francisco-based youth and college years spent in Valenica informs much of Keyboard City, which has a laid-back, beachy, hippie vibe that Santana himself best describes as the “Frisco mindset” in “Under the Sun.”
