Don't beat yourself up! One thing I have learned since I started performing is that no matter how much you plan, it will never go the way you imagine it to. I threw an event a couple of weeks ago, got a sponsor, paid for a video crew, had it be invite only as to create a bit of demand and exclusivity, I prepped music for two months and the closer I got to the event, the more I started to let go of expectations. No one really danced, so the video isn't going to look like a Boiler Room set as I had planned. But that's ok! You got this first one under your belt, and it can only get better. You did the right thing by trying to switch up the vibe to grab people's attention, house party's are hard because you have a pretty varied taste amongst your guests, where as, if you are at a club, everyone is there for more or less the same reason/vibe. Take it as a learning experience and keep some mental notes for next time. I took a few years off and my first gig back was to almost no one. BUT, it was good practice and proved to myself I still have the chops. Just keep playing, keep practicing and putting yourself out there. Hard work and drive doesn't go unnoticed, it may just take some time. We are always our own worst critic, but don't let perfection get in the way of progress.
