This is one I just heard about last week, and Mrs. Matty has already expressed her desire to go, which means 'probably' in our house. 

It's hosted by Grace Potter & The Nocturnals - who will play both nights, along with The Avett Bros., Sam Roberts Band, Galactic, Dr. Dog, et al.  All good bands with serious jam chops, but SRB is a recent standout for me.  I like what I've heard so far from GP's latest...

A pretty solid lineup, cheap tix  ($65 for 2-day passes...!!), and a good location in a very cool town and - as a homebrewer - one of my fave craft beer/brewpub scenes.  Plus, it's in September (14 & 15), which will mean lots of local color, fewer tourists and cooler temps. 

I suspect this weekend will sell out...and probably soon.  This might be the best value of the summer I've seen yet.
