There are more oldtime jams around the world than you can shake stick at. But how do you find them? Here's one great way. The diligent folks from Old-Time Open Jams have been quietly compiling a map of jams. Have a look and get out there! Old-time jams are in blue, festivals are red, and contests are purple. They've also included some Irish sessions in green if you're looking to branch out. Happy hunting!
