Formed in late 2004, reckless o.s. mixes all their musical influences (no fun at all, comeback kid, bigwig, satanic surfers...), trying to make aggressive and fast punk rock. The name of this band refers to not giving a shit about the scene and the trends, and to stay true to their influences and the music they like, resisting to change their musical style for what is trendy. They released a DIY demo in mid-2005, and now they are writing new songs and playing anywhere they can to make the name of reckless o.s. well known in the mexican punk-rock scene.
