I want to know the answer to the following question:
Where did the artist federation hold their annual balls?
All the background I'm provided with is that "From 1863, the artist federation kunstnerforeningen held annual Carnival balls in the old Freemasons lodge, which inspired Johan Svendsens compositions "Norsk Kunstnerkarneval" and "Karneval in Paris".". Is that enough to answer the question?
Answer: yes
