At the free Chilmark Potluck Jam this weekend, music fans will have a chance to bid on a one of a kind piece of local music memorabilia and to support a good cause at the same time.

The Chilmark Community Center was packed Saturday night, with every seat filled for the long-awaited return of the Chilmark Potluck Jam.

Another long-awaited Island tradition will re-emerge this Saturday, as the Chilmark Potluck Jam returns to the Chilmark Community Center.

A Chilmark Potluck Jam will be held Saturday, March 7 at the Community Center. The free musical community event begins at 6 p.m.

This Saturday, the 50th Chilmark Potluck Jam will brighten the windows at the Chilmark Community Center and spread its glow over a Martha’s Vineyard winter, as it has done for more than 10 years now.

Mandolins, masks, mashups and mashed potatoes greeted a horde of hungry listeners at the Chilmark potluck jam on Saturday night.

I really had no idea what to expect as I approached the Chilmark Community Center a little after 7 p.m. on Saturday night, but I hoped it would be like days of old when — as teenagers — we would make the long trek from down-Island to square-dance or listen to folksingers like Jesse Benton or David Gude. I was not disappointed.
