I DON'T know if you've ever encountered Crass, the anarcho-syndicalist punk collective - they're hard work. Impenetrable noise accompanies some of the most articulate anti-establishment lyrics ever written and every album is like a manifesto. Jeffrey Lewis is a major fan. Which is why he's tackled 12 Crass songs on his album 12 Crass Songs.

Shaved of their angry settings, the passion behind the likes of Securicor (Scares), I Ain't Thick It's Just A Trick, Punk Is Dead and Do They Owe Us A Living still shines through.

Lewis augments his acoustic guitar with other voices and sundry electronica to create a kind of acid-folk interpretation of the ultimate libertarian treatise.

This way, you'll be charmed into launching the revolution.
