Santana's Hispanic roots drive the majority of his tunes, his complex rhythms are typically comprised of a mixture of thumping, rhythmic hand drums, and china cymbals. However, what made him an effective rockstar was his ability to absolutely shred on the guitar. This wasn't an extremely common trait of the music that Santana grew up listening to, but the generation he lived in inspired him to make unconventional, yet still tonally classic tunes that rocked the ages and will rock ages to come.
