The Tubs (confuse with the Tubes at your own risk) are a Welsh band, relocated to London and now touring America for the first time. On first listen, their newest album Cotton Crown is a glorious wash of '90s college-rock guitar, a warm shower at midnight in a gently-lit bathroom, radio-ready four-chord nostalgia for hipsters and Blues Traveler fans alike. Taken at the most superficial, background level, it's an energizing shot of musical positivity.
