C'mon Dan, your reasoning is usually more sound (no pun intended). That's analogous to saying concrete and steel structures exist for a reason, so there's never a need to visit the formless wilderness of mountains or desert. Don't think anyone's advocating ambient 24/7.
I'd like to think you wouldn't have been among the bonehead Parisians hurling fruit projectiles in Stravinsky's direction at the Rite of Spring
roll-out. Plenty of room for the wide range of interesting styles of music out there.
[Sometime I should play you the tape I made decades ago, titled Something to Offend Everyone
, which kicked off with a mash-up of Petrushka
and a Tommy Dorsey Orchestra / Buddy Rich rave-up, and veered, ever increasing in tempo and volume, through various selections by The Who, Dead Kennedys, Sparks etc. -- I actually liked every track but found very few listeners who could last all the way through.]
