I remember when I used to be involved in a lot of wedding booking how much it meant to get a great band.  It used to be more of a roll of the dice kind of thing.  However, it has become much easier to get ny wedding bands because of the Internet these days.  You can audition them with out ever hearing them live if you so choose.  I just think that this is the next era of how you book music acts.  Which is going to completely revolutionize the industry to free up creativity to do some pretty cool things.
