Firehouse 12 is an amazing one of a kind experimental / avant jazz music venue with a bar downstairs and a recording studio and record label too. This is like, the kind of music you typically have to travel to NYC for, but in a super chill setting in NH, without NYC prices and crowds and related BS. May not be your thing, but if it is, it's as good as it gets.

If you wanna know what the music is like, google the folks listed in the spring jazz concert calendar: http://firehouse12.com/performance-calendar
