I've noticed that the new trend among  Anarchist Crust Punk and  Red/Anarchist Black Metal bands is their focus on matters of the spirit and matters of ecology. This clearly stems from the growing Anarcho-primitivism movement, while admirable, is something we cannot allow to completely take over the more street-based politics of the heavy music scene. These following bands keep more down home politics alive.

1. 

From the rivertown of Sheffield, Chewed Up play melodic anarcho punk/crust in the vein of Crass or Leftover Crack. Lyrics rage against societal pressure, conservatives, bigotry, and fascism. Excellent music.

A Sibat is a kind of spear used by natives of the Philippines. It shares the name with this one-man Crust Punk/ Black Metal project. The music has strong, strong late-era Darkthrone vibes and the lyrics are quite militant, name-checking the Pulang Hukbo ng Bayan (People's Red Army)

Jarost Marksa ,"Fury of Marx" in English, are one of the most fervent and idealistic communist bands in metal. Formed by Antoine Durand, a Frenchman living in Russia, in 2005, Jarost Marksa has issued a call for violent, proletarian revolution. They are a large cultural thorn in the side of Putin and his tyranny. They recorded an EP, entitled "We The People" in 2008. The EP included a cover of the classic Soviet ww2 song "Sacred War."

From the fertile grounds of the Canadian Black Metal scene, Anti-Freeze infuse mid-tempo, atmospheric black metal with strong anti-fascist leanings. One track from the Winter tape demo will be featured on an upcoming anti-nsbm comp.

Hailing from Ukraine, one of the worlds most tumultuous countries, Confront Stage offer blasts of anti-globalization street/crust punk. Listen to they. They're reporters with a backbeat.

From Sweden, Arrogant State play blown out, rawpunk in its most traditional form. Excellent vocals and lyrics about scene,  anarchy, and unity.
