Leeds's Brainwash festival returns for its fourth year in 2009 and features perhaps the best line-up yet. This year's edition sees the likes of Jaga Jazzist, Efterklang, This Town Needs Guns, Pulled Apart By Horses, Tubelord, BLK JKS, Vessels and many, many more wonderful acts.

It takes place across various venues in Leeds, including the Brudenell Social Club, Upstairs @ The Library, Mine, Pulse and Royal Park Cellars. Of course, it's a charity festival and money from this year's festival will be going towards Unicef, Leeds St Gemma's Hospice and Sheffield's Children Hospital.

We quickly quizzed festival organiser Haydn on the ins, outs and ifs about Brainwash Festival.

Where did the idea behind Brainwash originate from?

Basically, to put on good bands for a good cause. Simple as that. The Leeds scene played its part as well; I wanted to put together a diverse line up and Leeds had (and still has) a great pool of bands to make that work.

Why do it for charity, why not just put on a festival for your own amusement?

Originally it worked as part of the Oxjam festival, and it was a case of trying to help something important. It's still that same sentiment, and other charities have come into the frame due to personal reasons, as well as wider social ones. It seemed to make sense to try and let the profit go to something worthwhile, and still does.

Do you try and get the leading lights of the local scenes to play? Obviously there's a great amount of talent around that area at the moment.

Of course! However, they have to fall in to the category of the musical make-up of the festival, so certain types of bands wouldn't work. I couldn't put on a band I didn't like, so that plays a large part! We had This Et Al and iLiKETRAiNS play the first year, iForward, Russia!, Humanfly, Red Stars Parade and Vessels have been involved and we've got the likes of Grammatics in this year so we try and keep a strong local element to the festival, it simply couldn't work without it.

What do you think marks you out from any other festival?

The fact it's in Leeds makes a huge difference - there's just so many good bands here. The diversity certainly works, and the fact that we're not money driven in a profit sense, but in a charity sense.

There's some pretty great acts on the bill this year, how has the line-up changed and improved over the years?

I wouldn't say it improves as that would suggest that previous years weren't as good! We've just got different bands on, yet also like to keep some of the locals who play every year so there's still an element of familiarity and consistent involvement.

Any lessons learned over the last three years? I imagine there must have been a few tough moments at times!

I've learned one thing for sure: never expect there not to be tough moments! It's always pretty stressful, especially now in the week leading up to it. Luckily this year i have a tech guy on board so it's taking the heat off a bit.

Who are you most looking forward to seeing this year? Any unseen and unsigned wonders on the bill?

I'd be lying if I said I wasn't extremely excited about seeing Jaga Jazzist, they're pretty mindblowing. Unseen wonders? Probably lots for many people, discovering new bands is one of the most important aspects of the festival. People should keep an ear on Maggie 8 on the Saturday, and no one should miss We Vs. Death, who are quite simply amazing every time I see them.

And finally, hopes for the festival and a reason why people should come to this year's?

I hope that things continue to be fun and worthwhile, and that people continue to enjoy what's being put out there. People should come because there's a hell of a lot of great music, and the money you'll be spending will be helping people who really need it.
