THURSDAY, FEBRUARY 1 Tijuana No! at House of Blues. The most exciting thing about Tijuana No's recent hometown concert in TJ -- in which the band opened a giant arena show for rock en espanol demigod Manu Chao during one of his rare North American tours -- was the return of Cecilia Bastida, who's been busy in the last year backing up charismatic rising star Julieta Venegas. Although the group remained an explosive live force even in Bastida's absence, Tijuana No! is a much more magical and diverse combo with its full triumvirate of singers: Bastida, Luis Guerena and Teca Garcia. Bastida's serene vocals on the classic "Pobre de Ti," "Nadie Dijo Nada" and the band's hit remake of the Clash's "Spanish Bombs" always provide a melodic contrast to the radical, pro-Zapatista punk-rock raps of Guerena and Garcia on "Gente" and "Stolen at Gunpoint." All three singers are heard to great effect on the new LIVE AT BILBAO CD (BMG/U.S. Latin), which documents TJN's call-to-revolution broadsides performed in the heart of Basque country. With Bastida back for this concert at House of Blues, expect to see the world's biggest slam pit turning counter-clockwise during Tijuana No's festive, freaky melange of ska, hardcore punk, salsa, reggae, psychedelia, funk and metal. (Falling James) FRIDAY, DECEMBER 21 Tijuana No! at the Key Club. There are certain groups you wish would never announce officially that they're breaking up. Even if bands like the Clash and Tijuana No! -- whose music provokes as much radical political thought as it does frantic slam-dancing -- never perform live again or release another record, their mere existence as certified rabble-rousers makes the civil authorities nervous. So it's a shame that Tijuana No! are now calling it quits after a gloriously rambunctious decade of stirring up trouble. Most local gringos were blissfully unaware of the ska-punk-metal-rap-salsa-reggae combo's fertile existence (perhaps not realizing that TJN often sang in English, as well as in Spanish), but thousands of Latinos, here and in Mexico -- as well as celebrity collaborators like Fishbone, the Breeders' Kim Deal, Manu Chao, Negu Gorriak's Fermin Muguruza, Kid Frost and the Bad Brains' H.R. -- understood that this was not just some cool rock en español collective, but one of this region's greatest rock bands, period. TJN's secret? A triumvirate of equally charismatic, unique singers: Luis Güereña, the wickedly satirical heyoka clown-punk ("Somos Mas," "Gringos Ku Klux Klanes"); Teca Garcia, whose warms vocals exude a heroic grandeur ("Si," "Renace en la Montaña"); and the sweetly melodic Cecilia Bastida ("Nadie Dijo Nada," "Pobre de Ti").
