Via efeeme I read the news and leave it here for anyone interested. Not a fan of Andrés Calamaro, nor, the truth, Ariel Rot. Another thing to talk about them as composers, that would be another topic for another entry.
Andrew and Ariel did a mini tour together last year and the concert in question took place in Buenos Aires (Argentina) in December 2006.
I agree with the comment made from efeeme where there are explained as no record material that tour for many is already part of history that has not been reflected or recorded on DVD.
For this mini tour of Andrés Calamaro and Ariel Rot put their voices and were surrounded by Tito Davila on keyboards, Grecco Osvi on guitar, Candy Avello on bass and drummer Joseph Bruno.
