Life on the reef is beautiful. Lots of different creatures all live peacefully together here: parrotfish, swordfish, turtles, schools of sardines, an octopus, a seahorse, a mackerel, and an oyster. But then something terrible happens: a huge swarm of jellyfish starts drifting directly towards the reef! And jellyfish, as every fish knows, are dangerous! Fatal, in fact! At first, the four friends Mackerel, Seahorse, Oyster and Octopus don't want to face up to the danger - but then it's suddenly too late to escape! They're trapped! Just as they run out of ideas, something quite unexpected happens... In this family concert, Rufus Beck and the Bavarian Radio Symphony Orchestra conducted by Paul Daniel tell a hilarious and highly colourful story about the power to rise above oneself. The text, to music by Claude Debussy and Alexander Scriabin, was written by Katharina Neuschaefer, with illustrations by Martin Fengel.
