The trick is to make everyone, band and management, feel comfortable allowing taping.
Don't forget the venue too. Some venues can (and will) quash open recording regardless of any other permission. If they have a bad experience as a result of begrudgingly allowing one they won't allow any more.
Your read of some concern is important, as that read had to be founded on something.
The mode of distro is also a primary issue. Posting to a big torrent site (though I do that myself from time to time) is feeding the bootlegger/blogger machine and at the very least putting it into a Google search. If it is a band that has any (and I mean
ANY) commercial appeal/potential and there is some concern on the part of anyone in the chain of command nothing will hurt future opportunities faster than the recording being splashed all over Google searches, or worse turned into unauthorized product. If they have any commercial appeal and there is unreleased material involved then dollars to donuts some clown/s will be trying to sell it on the internet the same day it is posted elsewhere on the internet.
While I agree with the principle of sharing I'm always careful and rarely provide anonymous opportunities for anything that has any tinge of concern I'm aware of with rights holders.
If the concern is new material I'd wait until it's not new, though maybe send some files to friends who are discrete if you really need to share it now.
If the concern is the venue and you are likely to be a regular there then you probably won't want to post it far and wide.
On the management vs. band issue making recording or the distribution of recordings a wedge between them is not fair to the band, esp. if they're in the middle of things they really need to focus on.
