After years of living in different parts of the country, brothers Zack and Sam DuPont reunited to blend their songwriting and their voices. Since then, they’ve done over 300 dates and logged 30,000 miles together. They’re touring in support of their first album, “Heavy As Lead,” which one reviewer said “is crystal clear like a chilly winter, and thoughtfully crafted like an old antique.” The Vermont duo joins us to sing with voices described as “so pretty it hurts.”
