God help you. The older you get the harder it is to meet people in this city. Most people who go out to bars or music events just want to stick with their own crew and never like it when randos cut into their conversation. You mentioned you were musicians - try craigslist to see if there’s people who want to jam out with you. Be warned that there is a major practice space shortage in the city going on with one of the biggest facilities evicting everyone end of January - if you can stick to low volume/acoustic stuff you can do without a drummer you may have more successes
