Creating and building real community.

I'm curious if anyone has good resources for building local real world communities outside of the context for business purposes. I've been a musician for the past 15 years and have participated in my fair share of playing and attending shows all over Southern California.

One thing I always have found interesting is the multitude of communities that partake in doing live events and how those subcultures manifest. They are always in a constant state of flux and there the pockets of people are constantly evolving.

More recently, I've been thinking a lot about organizing events for my own sort of community, but I'm not really 100% sure where to start. I used to book lots of bands in the past but the landscape has changed radically, and now I'd like to do community building with a bit more purpose.

I'm looking for any sort of online research or book recommendations/lectures with people have vast experience building communities that are not primarily focused building community for monetary purposes. I only say this because it seems like a fair amount of businesses have co-opted the phrase community for their own gain, and I'd really like to try to learn about strategies people have developed for building community for the sake of community and nothing else.

That being said, if there is anyone who does music stuff in Southern California that's a bit more interested in chatting about this, I would love to chat.
