Cool, can you post it or is it private?
To me, as an auditioner, the most important video is one that shows whether the band is any good or not.
It's a private video. I have shared it in PM's before but for the moment, I have to run and don't have the time to dig up the link from Youtube, login, find the right playlist, etcetera.
It essentially covers issues like who I am (part-time, bass player). I select the songs after listening to everyone and giving them broad criteria for what makes a good song. I explain why it has to be this way (the need to sub players without rehearsal on my part). That people can play in multiple bands, but in return, I need a stable, simple repertoire that other players can learn fast, or on the spot at a gig. That I 1099, that people should cooperate with the client (a problem among some musicians), dress standards, when they should arrive and be set up, to budget extra time in traffic, the benefits of working with me (into my network of musicians, subbing opps). Rehearsal is at my place, no where else. Everyone should have own transportation. The need for musicians to be able to read charts -- not play entirely by ear. Commissions for people who book gigs, and if they book a gig for one of the bands I am in, that they are not in yet, they can play the gig with that band. Not to cancel on rehearsal at the last minute with reasons given. An agreement they sign that I can use video and pictures on website even if they leave the bands for any reason.
I got a lot of flak from Tbassers when I first put it out there, generally, the concept of an orientation video. A lot of flak. Accusations of being a dictator, or the use of the term "my bands" -- it seemed that any model other than the purely democratic model was sacriledge to some people. But a few people asked to see the video, watched it, and said it was reasonable.
I find that people actually want to be part of the experience after they watch the video because it shows organization, momentum, experience, and yes, standards and expectations. it also shows that we have gigs on the future.
People who don't want to pursue the audition after seeing the vide - that is fine with me. It means I have averted problems likely to rear their heads later.
All of the items in the video are responses to problems I have run into in the past five or six hears I have been doing this seriously.
