[quote]How would you compare it to free jazz though?[/quote]Free form jazz is certainly...weird. And it takes a certain mindset and understanding to enjoy it, and even then, it isn't something I enjoy all the time, and usually in small doses. Free form jazz rarely follows and structure, chord progression, or any discernible time signature or beat, which makes it hard to follow as a listener. But as a performer, it's probably one of the more "pure" forms of music, because you're just playing what you feel in that moment.
