I was able to get the YouTube link of this video which seems to be a Slipknot parody 😀 from one of my colleagues and I find it amazing that young kids like them play. They performed in The Cosquin Rock 2007.
Cosquin Rock is an Argentine music festival. It is held annually every February (summer holiday) since 2001 at Cosqu√≠n, Cordoba. In this festival, important national rock singers and groups would participate. In addition, some of the most important international rock bands (from Spanish speaking countries) like Spain, Mexico and Uruguay also participate in this annual event.
It must be a big achievement for them to be able to perform in such big event where 120,000 people attend each year. This is something similar to Fete de la Musique which has several acts performing simultaneously in different stages.
