'Closed jam sessions' are by invitation only.
Usually one person (you) takes charge of providing a venue and inviting the players.
There is always a set time for beginning and sometimes but not always a time that it will end.

Open jam sessions are an excellent way to meet other local musicians.

Closed jam sessions are most often facilitated by open jam sessions.
