I want to know the answer to the following question:
When did a PBS documentary air about the Bronx's music history?
All the background I'm provided with is that "The New York Times has identified 1520 Sedgwick Avenue "an otherwise unremarkable high-rise just north of the Cross Bronx Expressway and hard along the Major Deegan Expressway" as a starting point, where DJ Kool Herc presided over parties in the community room.". Is that enough to answer the question?
Answer: no
