Remember that band Santa Esmeralda, the ’70s one-hit wonder with the groovy disco remake of “Don’t Let Me Be Misunderstood”? After more than 30 years MIA, the band has reunited as the older and groovier Generation Esmeralda. The band’s sound blends Latin rock dance grooves with melodic hooks, impressive guitar licks and cha-cha with a splash of gypsy-infused Flamenco. The band returns from their tour of Brazil to play on Friday, Nov. 22, at Sausalito Seahorse. 305 Harbor Drive, Sausalito. 9pm. $10. 415.331.2899.
