A lot In Denmark: Punk/HC - Festival in Ungdomshuset, Copenhagen (but it's not 100% yet), Distorted Picnic DIY, Århus, Paramount DIY - Festival, Roskilde (not announced yet, but it's a tradition). Besides Denmark, there is "Punk illegal" in Göteborg, Sweden, "Play fast or Don't" in Czech Republic, "Obscene Extreme" in Czech Republic, "Zoro-fest" in Leipzig, Germany, "Scum-fest" in London, Great Britain... But a lot of theese festivals haven't announced anything yet for this year, so I guess you just have to lean back and wait And I, of course, forgot a shitload of festivals, and I proberly don't know half of the rest, so contributions to this list would be cool!
I know there's the alerta antifascista fest in Germany, where Light Bearer, the new band with ALex from Fall Of Efrafa, will play.
