Since then they’ve been steadily honing their craft, to the point where they will play their first headlining show at The Ark Friday night. Corndaddy has just released its third full-length album, "Heart of the Matter," which they helped finance by raising $3,551 via the crowdfunding Web site Kickstarter.
