I liked this demo so much. Specially because I was surprised, as it is has not a genre description or tags. I only thought, ah, just another folk spanish band, and when the music start (after 5 seconds)... I was nodding my head. :) I don't know it's influence, but I never listened nothing like this, except for Putos and Pontapés (from Portugal). But Los Muertos de Cristos rocks more. I'm waiting for more Los Muertos de Cristo songs here on Jamendo :) Ah, the recording has some undesirable mutes (I think) eg. in -1:57.
