Some pics from the now defunt Northstar Bar jam in Rochester.

Area 52 - Northeast Minneapolis. I've never been to this one but I've talked to people who have so I can assure you it is real. According to their website, Area 52 is a musicians cooperative that has an open jam every Friday night. There is never a cover and nothing is for sale. The link above takes you to their MySpace page which has a link address to another site with a link to a forum.
Group Therapy - The Whiskey Bones jams have been cancelled (????).
Jerk Jam - This has been a fairly regular Twin Cities area open jam though they are apparently taking a sabbatical. Check out the link for the latest on this jam. NEWSFLASH!!! THE Jerk Jam continues Thursday Dec. 11th at the Blue Fox in Arden Hills.
