I have been in a band for a year where we have played dozens of gigs in a small, small bar and my chops and confidence have greatly improved. This Satuday though, they are doing a grand opening of an outdoor ampitheater here in town that seats up to 6,000 and we play the final one hour slot that evening after multiple local bands and artists play throughout the day. I don't think there will be anywhere near that number of people. Probably in the hundreds at best. BUT we will be fully miked and mixed by a professional sound company for the first time. The band went out there last night and the place is BIG. Everyone commented that we will be nervous. I have historically suffered from some pretty big stage fright episodes and am already a little bit uptight. We have rehearsed the set a lot and it's tight. We won't play again until Saturday though. Any advice?
