"What you will mainly find is Mexican rock, from the time of rock n' roll of the likes of César Costa and Los Hermano Carrión, to lps of bands like La Revolución de Emiliano Zapata, Three Souls in My Mind, Caifanes, La Maldita Vecindad, the early works of Javier Bátiz and a lot of other things."
Really? Has the author of this piece ever been to El Chopo? You can find this type of music at El Chopo for sure, but it isn't very easy and only a few sellers deal in this kind of music there. El Chopo is mostly metal, punk, and goth, with a minority of sellers dealing in other things like rock mexicano, jazz, blues, reggae, and techno. Sorry Chilango, but you need some better reporters.
