We’ve got the need for mead! It’s an hour of swords and fjords, with music from movies about the Norsemen, including “The Long Ships” (Dusan Radic), “Prince Valiant” (Franz Waxman), “The 13th Warrior” (Jerry Goldsmith), and “The Vikings” (Mario Nascimbene). It’s the perfect mix-tape for your dragonship, this Saturday at 6 pm.
