Music can be performed. Or rather, performing music is way less boring for an observer than performing painting or sculpture. Of course, speedpainting exists, but performative art is more resistant to being obsoleted by technology.
in contrast, the whole point of paiting or a sculping is the final completed artifact.
What I'm trying to get at, is how recording technology "defeats" the purpose of music as its performace; and so, irremediably splits it from it's source (its origin, the composition of the music). I suppose improvisation remains; but highly constrained within prearranged structures (a la "AB[improvisatino goes HERE]C") like in jazz.
I do not understand how hyperpop nor DnB are supposed to be a response to what I'm trying to get at (then again, I'm just now barely conveying my point... I hope.)
