'Yeah, Crystal Mate' is the title of this short clip from Sennen's Seb Smart, filmed by Sam Breeze over the course of a couple of backlit January sessions in the crystalline Cornish cold. So much attitude! Such swagger! But Who The Fuck Is Seb Smart? we hear you ask. There was once a time when we didn't know either, so we took the trouble of asking him, and this is what he said. He seemed like a jolly nice chap.
