June 11. Despite the understated, low-key drama of their music, through their actions indie luminaries the National have never been quiet about their support for progressive social causes; the Cincinnati-by-way-of-Brooklyn band's charitable efforts have included activities to aid underprivileged Queens families, a Boston nonprofit health-care organization, and the preservation of Tibetan culture. And then there's this concert at MASS MoCA, whose proceeds will benefit the Massachusetts arts center itself and the Hawthorne Valley Association, the parent organization of Columbia County's Hawthorne Valley Waldorf School and Hawthorne Valley Farm. The latter beneficiary's plight hits home for the group, as at least one of its members, multi-instrumentalist Aaron Dessner, is a local resident. With Yassou. (Dan Zanes's Lead Belly Project moans June 18; the Suitcase Junket unpacks June 25.) 7pm. $45. North Adams, Massachusetts. (413) 662-2111; Massmoca.org.
