I've only done one gig, and it was moderately sized, indoor. Too many people for me. I also had trouble hearing myself on the amps, so I sucked. Over 100 people induced stage fright. Small and intimate is best for me.
I like music Festivals, The crowd is diverse, and you can actually see people in the sunlight. A lot of bars and venues are dark and dim, i like that a lot, but going outside to a large park is a nice change of vibration
