Was at this fest last year, and despite a low turnout, it was a great fest. Lots of the old NWOBHM from back in the day playing. And the money goes to charity. £25 for a weekend ticket is an absolute bargain.
Takes place in Bury, just outside Manchester. About 30 mins on the Tram.https://www.facebook.com/grimmupnorthfest/
