Inspired by praetorianus.....Can you think of any completely brand new styles of music, that are not variations or progressions of past music, that have emerged recently? Say after 2000? (If so please share)
No, but as I outlined in my poll, when electr(on)ic instruments were invented, we got new styles. The E guitar led to rock, synthesizer and sequencer to modern pop, dancefloor and techno. I've just seen no new inventions since then.
So we got salsa music right? How about some guac?
No? All music is derived from something else, isn't it? You could argue the sound humpback whales make while mating is just "World" music.
There are none.
