Hard to choose really, it's between two gigs though :
Gig 1 : Cerberus Cell - Melodic Death Metal
I organised the gig, rented the venue, got the support act sorted, organised and ran the lights and PA system. It was held in what is now my home town, the crowd went absolutely NUTS! Mosh pits, walls of death and a stage invasion. I was buzzing for days! If I remember correctly @Thurbs was there
Gig 2 : Faint Lines - Indie
A small venue in Bedford, was actually the second gig of the day (the first being on the list of the worst gigs I've ever played). The band were absolutely note perfect and everyone was buzzing. People coming in off the street, paying the entry fee just to watch us. Incredible night
