literally anybody involve in art forms will at some point try to differentiate himself from norms and standards. someone who dreams to follow the line on the ground doesn't typically decides to become an artist. I've always been an unskilled amateur in anything I've touched but even then I was looking to do something "new", to create! this has always and will always be the situation for artists. what has changed is the accessibility for the average consumer. in just 3 generations, everything changed, from having music at home being only a thing for rich people and/or families playing themselves, to freaking internet on our cellphones and every audio apps and websites spying helping us discover new stuff we might enjoy. that also affects the artists around the world who get to widen their horizon, but they were going to do different anyway.
ultimately every band will be part of the Blue Man Group and hit on PVC pipes, as that's obviously the endgame in term music and art form. but in the mean time, we mostly just get to see more of the world's real diversity. my point being that IMO it's always been there. including all the stuff we pray will remain underground forever. ^_^
shouldn't this topic be renamed as "intellectualized jazz conversations"? I remember a few timid attempts for something else(including from you who started with a pretty wide range of genres), but it didn't last long.
