The Ark has to be one of the most intimate of all internationally known music venues. It's like the folk version of the Apollo. Not only does everyone play here, but everyone plays better. The Ark is a nonprofit organization that has set out to enrich our spirits through the preservation, education and presentation of folk, roots and culturally ethnic music and arts. And the venue succeeds with organic grace and folkie panache.
