unfortunately, I didn't have any detailed or official informations on this tribute before it was organized. Otherwise I would post it on this forum as soon as possible. I live in Central Europe and sometime the communication channels with Mexico are very slow. Also fluency of Spanish would be more helpful. I think many other artists would like to participate and pay tribute to this extraordinary person and musician. At this moment I don't know any other way to see the pictures from this event. But I will ask Julio Cesar, maybe he can e-mail you all the pics.
All the best and have a nice time.
