response: I'm unaware of any and another about free jazz is that defining it is difficult as it was never a distinct genre.
original_response: It is hard to explain it because it cannot be define and was never really a genre of music
history: I really love jazz as a musical genre.  Do you like jazz? I'm not but do you like free jazz? It got made around the 1950s to the 60s. I have never heard of free jazz.  What are some of its most popular artists?
knowledge: As its name implies, free jazz cannot be defined more than loosely, as many musicians draw on free jazz concepts and idioms, and it was never completely distinct as a genre.
