I don't want to come over as offensive or difficult, but if the thing you want isn't available locally, start your own.
There wasn't a local Bass Bash to me so I organised it and our third one is going to be next year. I also wanted a jam night and I'm in discussions with the local as to when they want to host it and we should be starting in the new year.
I'm not sure where all this community and social organisation has come from mind, I'm normally an insular and asocial person! I must be getting old...
