I want to know the answer to the following question:
Why did many post-punk artists produce and release their own music?
All the background I'm provided with is that "Additionally, in some locations, the creation of post-punk music was closely linked to the development of efficacious subcultures, which played important roles in the production of art, multimedia performances, fanzines and independent labels related to the music.". Is that enough to answer the question?
Answer: no
