Night has fallen on the Grant Museum of Zoology, the doors are closed and the museum staff have gone home, but something is stirring. The bats wings are twitching and the pickled moles are uncurling because the world's only improvising opera troupe have snuck in at twilight and with your help will sing the specimens to life. Explore the Grant Museum and immerse yourself amongst the beasts, insect, fish and birds on display and enjoy musical performances made up on the spot by Impropera about your discoveries. No score, no story and no safety net. What is performed is up to you, join us for an evening of Muso: Singing Treasures to Life.
