Track Dogs bring two decades of genre-blending brilliance to close out Nansledan Arts Festival. This Madrid-based outfit layers acoustic guitar, electric bass, trumpet, and cajón beneath four-part harmonies that shimmer with unexpected depth. Their sound — sunshine melodies wrapped around darker themes — draws from Americana, bluegrass, folk, and blues with complete disregard for boundaries. Veterans of Glastonbury and the Royal Albert Hall with 11 albums behind them, they've mastered the art of getting feet tapping before you realize you're already dancing. Midsummer celebration with a bar at St Michael's Church, Newquay.
