I don't know about you but I've not been on a proper treasure hunt in a long, long while. One where the treasure isn't food or alcohol, anyway. Green Man festival have just unveiled one - and one where the prize is something worth winning. Guess it wouldn't be called treasure otherwise...

Here's how it goes. Lone Wolf, who recently released The Devil And I, is the person behind it all. In the surrounding environs of the festival in the Brecon Beacons, there is a special single from the man himself. It's a 7" vinyl of a track written specifically for this competition. All you have to do is find it.

That sounds pretty tough. But fear not because there are clues. Wouldn't really be a very good treasure hunt without clues now, would it? To try and work it all out you'll need to watch the video for Lone Wolf's new single '15 Letters' which is available to view only on the official Green Man website. Click here to visit.

There are 15 clues hidden in the video which will aid you in your search. And what do you win if you manage to find the blasted thing? You win an IOU for a whole year's worth of Bella Union releases, probably worth sniffing around for.

This year's Green Man festival takes place from August 21-23 in Glanusk Park, Brecon Beacons, Wales. There are a whole host of wonderful artists playing this year so click here for more information.
