I want to know the answer to the following question:
What was unique about Odeon's 1909 release of the Nutcracker Suite?
All the background I'm provided with is that "German record company Odeon is often said to have pioneered the album in 1909 when it released the Nutcracker Suite by Tchaikovsky on 4 double-sided discs in a specially designed package.". Is that enough to answer the question?
Answer: yes
