Mezzo-soprano Melis Jaatinen sings a Corona-shortened and choir dismissed “Messiah” in Halden, Fredrikstad and Moss, 27, 29 November and 3 December, together with Stellis Polaris’ artist Berit Norbakken and great colleagues. Den Norske Blåseensemble and conductor Knut Johannessen will make this special, indeed.
