Brussels is offering people in the city a unique and free experience this month, a short up-close-and-personal live classical music performance in a transparent box just big enough to fit a grand piano and three people. Barely 15m2 and constructed entirely out of glass, the smallest concert hall in the world is the brainchild of the annual classical music Klarafestival, taking place in Brussels and Flanders until 30 March. Sophie Detremmerie, managing director at Klarafestival, explains all.
