Music festival of the week: Green Man Festival, Glanusk Park, Crickhowell, Powys

Phosphorescent is one of this year's main draws

Basically the dogs' bucolics when it comes to fine beards, brews and bands, the Green Man has blossomed over 10 years without losing sight of its grassroots principles.

This year, main draws such as Band of Horses, Kings of Convenience, Villagers, Midlake and Phosphorescent are all made of the alt-rootsy stuff the festival sprung from.

Further afield, anything goes so long as it's in the festival's independent spirit, be it beats mavens Erol Alkan and Andrew Weatherall in the Far Out After Dark arena; noise mavericks Swans and F*ck Buttons; or Thursday night headliner – and figurehead for the free-thinking – Patti Smith.
