This is perfect evidence that locking musicians in a room and letting them get on with it is the best idea ever. That’s what happened when the eight members of this ‘supergroup’ were picked for the Burnsong project, and the result is this sumptuous, accomplished and sometimes strange album. The nominal focal points are King Creosote, Karine Polwart and Emma Pollock who, alongside a stellar supporting cast, deliver a touching, melancholic and beautiful collection of folk-flecked pop (with the occasional rap diversion), from the hard-nosed grind of ‘Blood, Ice and Ashes’ to the plaintive and moving ‘Sorrys’. More than a mere sideshow.
