Riña hail from Mexico City and play harsh, desperate-sounding hardcore punk. Things are out-of-control and border on the slapdash, but a sense of furious purpose prevents it from all collapsing in on itself. The music’s trebly to the point of antagonism and the raw, sneering, rasping vocals convey so much hate that they immediately set your fight-or-flight impulses racing. It’s nasty, alienated and confrontational – exactly what you should be wanting from a punk 7″, basically.
