For any touring band, it is highly unusual for the group to return to Tucson less than five months after appearing before a rousing audience.

Then again, Café Tacvba is not just any ordinary band. The Mexican rock quartet, one of the most critically acclaimed musical groups on the planet, returns to the Rialto Theatre Sept. 5 to promote its latest recording, ""El Objeto Antes Llamado Disco."

"It is was a good pretext to return to Tucson," said Rubén Albarrán, the group's lead singer, known for his long, natty locks, quirky voice, animated stage presence and occasional name changes. He has called himself Anónimo and K'Kame in the past.

The other three band members include Emmanuel Del Real, and brothers Enrique Rangel and Joselo Rangel, all of whom, including Albarrán, met as university students in Mexico City.

La Estrella de Tucsón caught up with Albarrán who was in the Yucatán, a week before Café Tacvba launched its U.S. tour, which began Aug. 29 in San Francisco.

The new recording, the group's first in ??? years, was released late last year and produced by Argentine Gustavo Santaolalla, who has produced many of Tacvba's eight studio recordings. "Objeto" reached the top of the Mexican charts and earned strong critical applause in Latin America, Spain and the U.S.

Like all its previous works, "El Objeto" has its own unique sound.

"I think it is important to change our sound," Albarrán said.

"Objeto" is a richly woven interplay of guitars, bass, drum, synthesizer and digital sounds. It's ambitious and complex, far apart from the more simple pop sounds of most rock en español groups. Hints of music from the Andes and the Middle East gives "Objeto" added world texture.

Albarrán said the group attempts to capture the band's essence and personality in the time the record gestates from early ideas to final release.

"Each recording is done in the moment," he said.

While Café lives in the moment, most of its fans live in the group's past. A concert with Café Tacvba is a sing-along love fest as the the rockeros groove on its many past hits - Chica Banda, Rarotonga, "La Ingrata" "El Ciclón," "El Puñal y Corazón," and covers of "Ojalá´ que Llueva Café" and "Como te Extraño Amor."

While Café's next Tucson performance will focus on the new album, Albarrán promised the show will be sprinkled with some of the old rolas.

And there are many old rolas since the band formed. Or as Café likes to say it has been "Metiéndole al taconazo desde 1989."

The four members emerged from the Mexico City suburb, Ciudad Satélite. Fans of English goth and American punk rock, a similar mix that other Latino rock groups were experimenting with in the 1980s. But Café fused its punk rock with Mexican rhythms and sounds - norteño, ranchera and huapangos.

The sonic melange was an instant hit with young Latinos. Over the years the group has attracted a worldwide following.

Next year los chavos will celebrate 25 years, a long time on some calendars.

Albarrán laughed off the fact that he and his cuates are not as young as they used to be. The music, however, will keep them young and fresh, he said.

"Ya estamos viejitos pero el rock 'n rol nos mantiene," dijo.
