Over at his Impressions of Vince blog, my colleague Derrick Bang has posted his comprehensive list of 2013 concerts. Check it out and see if there's a concert in your vicinity.
Personally, I went to one of the Heather Pierson Quartet's A Charlie Brown Christmas concerts last year and really enjoyed it. I recommend them, if you live near one of the locations of their eight shows in New Hampshire, Maine, and Massachusetts. But I'm sure the other groups put on good shows, too!
