Alternative rock band Wilco is based in Chicago and has a worldwide following, but when they take the stage in Raleigh tonight, it will be in support of a North Carolina-based nonprofit called Farmer Foodshare. The band is donating a portion of its concert merchandise sales to the organization, which collects fresh, local food and monetary donations for hunger relief. Host Frank Stasio talks with Wilco lead guitarist Nels Cline and Margaret Gifford, founder and executive director of Farmer Foodshare, about their partnership to end food insecurity in North Carolina and Wilco’s new CD, “The Whole Love.”
