Against a background of increasingly corporate-driven festivals, Green Man Festival stands out as a fiercely independent alternative with a distinct ethically-minded twist. This August, it returns to Glanusk Park in Wales, its home for the last few years.

Top of the bill is Van Morrison a true legend with a career spanning over fifty years whose vocal talents will be a real treat for festival-goers. Also featuring will be Canadian singer-songwriter Feist, post-rock from Scotland's Mogwai, New York indie rock band The Walkmen, a newly-reformed Dexys and The Tallest Man On Earth (not actually especially tall, but an exceptionally good songwriter). There's also DJ sets from Mr Scruff, Time & Space Machine, Richard Norris, Psychemagik, Airhead and more late into the night and through the morning in the Far Out After Dark area.

It's not just about the live music either (though that's only a very small taste of the musical talent on offer). There'll be comedy on offer until 2 in the morning from names like Holly Walsh, Zoe Lyons, Robin Ince, Josie Long and many, many more. The unique Einstein's Garden will feature a fusion of science, art and nature, including workshops, installations and performances plus more music and comedy. And Chai Wallahs will be back, with DJs playing reggae, rap, blues, jazz, hip hop, dub and dance every day until 5am in a Bedouin marquee serving quality food and drink. What more could you want?

Adult tickets are £145, including weekend camping but concessions are available. For more ticket details, a full line-up and everything else you need to know, see the Green Man Festival website.
