This concert has been misidentifed for years. It was sponsored by the Center for Solidarity and Philanthropy of the University de Monterrey (UDEM) but it was held in their home town of San Pedro Garza Garcia, in front of the San Pedro Auditorium which is clearly visible behind the stage at times.
They were playing an after-event concert for the 1000+ Juniors from local high schools who were attending a meeting called YoLoVivo that warned them about the dangers of gangs and drugs, and provided them with training and education consultants. The girls were tired after spending all week working on their first album (XXICB), and had to breathe paint fumes from a spray-paint artist working next to their stage.
