Dates confirmed as 11th-14th June. No mention of the venue, but hopefully it will be the Custard Factory again.
It's being billed as "Limited Edition" like last year's was, however this year appears to be four nights instead of last year's two.

Some line up is being announced and tickets go on sale this Friday. Cracking festival!
Anyone heard any line up rumours?
