The majority of my playing happens in my room, alone, in stocking feet.
However, a few times a year I'm at historical events, which for me in inseperable to playing music with my friends. In the evenings we get together and play tunes, tell jokes and visit. Usually there are several guitars, one or two fiddles, maybe some smallpipes, fultes, whistles and at least one bohdran. Maybe in a while I'll be able to play the concertna?! It'l be awhile, though. First I have to actually get one!
There is a weekly session not too far away from where I live, but I've only gone to listen.
