Unbuckled Records, brainchild of Longmeadow’s David Smith, is up ‘n’ moving to Boston. To say farewell, Northampton’s The Elevens nightclub is hosting Dog Day Festival, an all-day musical event featuring some 25 bands. Smith, a longtime local and regional music supporter and promoter, has summoned bands from all over the Northeast to provide the soundtrack for his departure, including Maker, Citystate, Make The Rules, Avely, Arrows Over Athens (pictured), Like Violet, Trophy Wives, Bellwether, Foreign Tongues and several others. Elevens booker and part-time Swill Merchant John St. Onge is excited for what he’s calling the “mini-festival,” which serves up live music this Sunday for nigh on 12 hours.

Sept. 1, 3 p.m., The Elevens, 140 Pleasant St., Northampton, (413) 584-4100, musicattheelevens.blogspot.com.
