Rodrigo Sanchez and Gabriela Quintero have spent much of the last 20 years carving out their own lane of nuevo flamenco, applying nimble-fingered heavy metal guitar techniques on nylon-stringed acoustic guitars. The duo builds lightning-quick instrumental melodies atop syncopated percussive rhythms, creating stadium-sized songs with just a pair of flamenco guitars. They’re joined by the Mavericks, a Nashville-based band that takes a similar approach with country music, incorporating Latin and rockabilly influences into their Texas-sized country western sound.
