Music that break Parameters

First of all, I have to say that, in my opinion, there is only one band that must be considered as the ultimate broken-parameters band: The Beatles. You like them or not, you cannot deny the fact that they have influenced almost every band since their formation, changing their musical composition dramatically through their active and short period as a band. The band from Liverpool was received dichotomously by the audience: from one side there was the female young girls that built the “beatlemania” thing, shouting and crying when the musicians were in front of them and making everything that was needed to stay closer to the Fab-Four. And, from the other side, there was the specialized critics that considered the band as only a teenage-thing, that it was not anything more than that. And they was right. I mean, the only revolutionary thing that had The Beatles in their beggining was the histeria that brought to the (mostly female) audience. The real revolution came with the years, when this guys started to experiment with psychotropic drugs while they were composing their music, and by this time they started to be considered as a mature and psychodelic band that left behind the commercial pop side to make an incursion to more complex and deeper music.

I think that the bands that break parameters have generally a well stablished political side: the side opposed to the traditional conservatism, because they have to have necesarilly an opend mind to new things.

Finally, I think that in the national scene Los Jaivas could be considered as one of this bands, because they mix in a interesting way the folk latin music with the progressive rock, with a beautiful outcome that can be appreciated in Cds like El Indio or Alturas de Machu Pichu.
