In about a week, I will play at a gig with 8000 expected viewers. I`m subbing for the band, been practicing and learning their material since 3 weeks, and I am only starting to feel confident in the practice room by now. My plan is to play the songs 3-4 times a day for my remaining time to get them etched in as deeply as possible. I have never performed in front of that many people. I fear I might be extra nervous. Any tips how to deal with big crowds?
