Singer/songwriter Jake Armerding is scheduled to perform a benefit concert for Winchester Got Lunch at the Griffin Museum of Photography on Wednesday. Armerding, who launched a Community Supported Art program in 2011, is a regular on stage at Club Passim in Cambridge, plays a scorching fiddle in the bluegrass band Barnstar!, and contributes multiple instruments to his ensemble The Fretful Porcupine. He is the author of five albums of original music, and has shared the stage with Bela Fleck, Nickel Creek, Josh Ritter, David Wilcox, and Toad the Wet Sprocket. Armerding will be joined on stage Wednesday by Zack Hickman of Somerville, the founder and force behind Barnstar!, and Winchester resident Annie Bartlett, a classically trained violinist who serves as a trustee of the Winchester Community Music School. Winchester Got Lunch strives to provide healthy lunches for any child who has a need for subsidized meals during summer vacation. The program is a collaboration of churches, town and school employees, community organizers, businesses, and individuals. “It is a true testament that when there is a need, people come together to help,” said Sharon Johnson, copresident of WGL. As a result of community support, 100 percent of the ticket sales for Wednesday’s concert will go to support WGL. “Everyone should have access to real food, and it’s amazing to see such a strong outpouring of support,” said Armerding. “I’m thrilled to integrate Community Supported Art into the fund-raising effort for WGL.” For more information on Armerding, visit www.jakearmerding.com.
