Concert Etiquett!! (going to my first show)

Hello! I'm going to my first show in march! I'm excited but clueless too... I don't want to bother the other audience and I want to enjoy it and I don't wanna be involved in fights or anything! Any tips or etiquette that people should follow that I should know? Thank you!
I'm going to see Dean, Miso, 2XXX!, OFFONOFF, members of Club Eskimo! I'm very eskimo, especially Dean because I love him so much!
