i've barely risen and am not yet ready to shine, but i will offer the small thought that there is something intrinsically authoritarian about showbiz - it is one way transmission
the extent to which deejaying becomes a show - with the deejay visible on stage, the Panopticon in reverse, all eyes pointed in one direction - is a relapse into showbiz
and the ultimate logic of that actually took EDM deejays into residencies in Las Vegas, world capital of showbiz
you can see the same dynamic repeating through rock history - bands in small clubs, on the same level as their audience, inhaling the same air and sweat, the same pheromone exusions... moving into big halls... and then into arenas... that move almost demands more showbiz elements (stage sets, better lights, props, choreographed routines, more razzle, more dazzle), and the audience stops being a community and becomes the proverbial "bums on seats", gawping at the spectacle
then the counter reaction - first pub rock (you can smell the Watneys on the singer's breath), where there isn't even a stage, just the floor - then punk
and so on - an endless dialectic (grunge is another anti-showbiz, back to the people shift - a rebellion against stage lighting, even)
youth popular music self-defines as the opposite of showbiz, of light entertainment / variety / cabaret - the stuff grown-ups are into (cos they need to be distracted, relaxed)
but then it gets bigger and starts to itself as just a new form of showbiz with a kind of formalized informality and slightly more explicit sexuality than Vegas / Broadway / the West End
Queen are a good example of this - rock become schlock, but also having an authoritarian subtext
it's no accident that they gave themselves a regal name, played with opera (music of the ruling classes), happily performed in South American countries with dictatorships, played Sun City
