After all that French elegance, what better than the piece said to be the loudest piece of classical music of all time, a spectacular depiction of the eruption of Iceland's angriest volcano, Hekla, scored for four sets of rocks hit with hammers, steel plates, anvils, sirens, cannons, metal chains, choir, large orchestra and organ? Genuine heavy metal music! It's a thrillingly no-holds-barred piece, intended to stun the listener into awe at the power of nature, by Iceland's most famous composer, the remarkable maverick Jón Leifs. Listen to it here.
Word of warning: Don't be lulled into turning your volume up too high by the opening couple of minutes!
