Ticket details have been announced today. Takes place over the weekend of 19th-21st September. Acts haven't been confirmed yet, but they're usually decent enough and good value for the ticket price.

Here's the last one: http://www.mtv.co.uk/mtv-crashes-plymouth/cast

Tickets are very cheap, £6 for the "live show" (pop/rock acts, I assume) and £11 for the club night.
