I want to know the answer to the following question:
George Golos references what two musicians when claiming Chopin's nationalism was overrated?
All the background I'm provided with is that "George Golos refers to earlier "nationalist" composers in Central Europe, including Poland's Michał Kleofas Ogiński and Franciszek Lessel, who utilised polonaise and mazurka forms.". Is that enough to answer the question?
