Shatter Chayanne's attendance record by 20,000.

Mexican rockers Cafe Tacuba established an attendance record at Mexico City's Zocalo, with more than 170,000 people showing up for a free concert June 4. The previous record was held by Chayanne, whose free concert last year drew 150,000 people.

Tacuba is promoting its most recent album, "Un Viaje" (Universal). As is the case with previous albums, lead vocalist Ruben Albarran has changed his artistic name to Zizou Yantra to coincide with the album's release.

At the same time, Tacuba's previous label, Warner Music Latina, also released "MTV Unplugged," a recording of the group's MTV Unplugged performance, originally recorded in 1995.
