This is an Exceptional Story, an additional piece of content for Fallen London that is available to subscribers, or for purchase for an additional amount.
This story centers around a revolutionary (called the Growling Radical) who was essentially exiled from London for a time. He wants to come back and put on a performance that will shock the powers-that-be.
And that's all that really happens. There aren't too many twists in this story; he asks you to help his song, he puts on the performance, and you can influence a bit how things go.
In a recent survey, out of the 100 stories that require money, this story ranked 90th, one of the least popular. But the author has also written a story in 6th place, The Brass Grail, so it seems less like a skill issue and more like just an idea that didn't work out as well as hoped.
