El extraño del pelo largo

Although it's a very interesting film about the begginings of rock/beat music in Argentina, it's mostly seen from an hegemonic and corporate point of view. Once the hippie scene became mainstream in that country, film producers decided to give it a chance and show a very clean and family friendly rendition of the origins of beat music. It's pretty much shallow and a huge piece of fan service for early 70's hippie-alligned youth. Still, it's very interesting to see the idiosyncracy of argentinian consumerism towards music and arts in general.
