When is a benefit concert more than just a concert? When it’s a show put on by Concord native and Grammy-winning Dan Zanes. We talked with Dan this past March when his old rock band the Del Fuegos reunited for a series of shows. His current band, Dan Zanes and Friends, tours the world playing what he calls “exuberant, handmade 21st century social music for enthusiastic crowds of kids and kid sympathizers”. This Saturday he’ll be back on stage in Concord along with several local musicians for a benefit for the Friendly Kitchen.
