Cardboard Sessions is a free-form, jam-format video series where world-class artists play fully functional instruments built entirely from corrugated cardboard. No setlists. No overdubs. No second takes.

Created by Signal Snowboards in partnership with Ernest Packaging Solutions, it's the spiritual cousin of MTV Unplugged and NPR's Tiny Desk. Intimate, stripped-down, and impossibly raw. The contrast is the whole thing: humble recycled boxes in the hands of people who can actually play.
