I'm going to this one, hope they play Killing Moon.
I went to this one, more from this year in my gig history for 2010. Part of a list of all the gigs I went to from '87 to '19. It's an obvious step from my Best gigs of all time blog post. Yeah I know it's very nerdy, let's let that go though, I'm enjoying remembering this stuff.
It's on The Leas, overlooking the channel, though you'd not realise that when you're inside at a gig.
