CAFÉ TACUBA may be the best indie-pop band you've never heard, but that doesn't keep the Mexican quartet from selling out large theaters around the country and packing them with multicultural audiences. The group's following includes everyone from Spanish-speaking fans who can recite all the lyrics to English-speaking fans who simply love the music. The key to Café Tacuba's success is a series of brilliant albums, including 2004's Cuatro Caminos. A tour for its new album, Sino, lands at the Masquerade Thurs., DEC. 13. $30. 8 p.m. 695 North Ave. 404-577-8178. www.masq.com.
