Well, to be honest I had never heard before of neither Zatiro (Chile) nor Dispara (US). Recently, I recieved an e-mail from Zatiro that was asking me to upload their split with Dispara. I thought that it would be nice to help them (my way) to spread their sound. So, getting the point, Zatiro play punk/hardcore having fast and mid-tempo (sometimes melodic, sometimes not) parts scattered in their songs. The only "bad" thing (in my opinion) is that vocals are too loud (according to other instruments) and as result the music is a little bit buried. Dispara now, play d-beat punk bringing to mind Besthoven. Nice guitar riffs with raw vocals draw your attention from the first song. A worth-hearing split that needs to be checked.
