I find this kind of insulting.

Like they think we won't be able to behave ourselves or have never been to anything but rock concerts. I didn't hear of any mishaps in ATL.

Hey, it's not 1992 anymore and we're adults with real jobs and mortgages.

Whatever.

Apparently, according to @briannati who was at the Atlanta show, there are unfortunately a few Phish fans with limited experience in symphony orchestra concert etiquette.

(And even n00b concert audiences need to be told not to applaud between movements of a symphony).

As seen on some of the YouTube videos, some of the ATL fans also got a bit raucous, especially during YEM.

Anyway, probably better to explain what's expected of the audiences than to have ushers and security confiscating phones and cameras and generally giving everyone the stink eye while the show's in progress. Everyone will have a better time, being forewarned.
