Led by Peruvian-born vocalist and percussion master Braulio Barrera, who earned a Grammy Award for his work with the Pacific Mambo Orchestra, Somos el Son is a relatively new addition to the Bay Area Latin music scene. Launched four years ago, the potent 10-piece combo plays a dance-inducing repertoire of classic salsa and finely wrought originals. A well traveled and highly versatile musician who played cajón on Gustavo Santaolalla’s soundtrack for the 2004 film The Motorcycle Diaries, Barrera has attracted a world-class cast of players, including trumpeter and Pacific Mambo Orchestra co-founder Steffen Kuehn.
