The "ringing in your ears" you experienced shortly after your post was the drone of all of us chiming in together after seeing your "never returns my phone calls" We've ALL been there. Running a business owned by a corporation who's home office is a thousand miles away is totally different than a business owned by a family, or individual who's usually if not always there. The latter, unfortunately, is almost non-existent anymore, while the corporation, regardless of whether it's privately or publicly owned, looks primarily (if not only) at the bottom line.....$$$ Guess what category is the easiest to cut?
Some long time ago, I performed for a nearby assisted living facility (privately owned) where the AD told me that she was told by the owner "Who is that guy? That's the kind of music I want for MY PEOPLE! You be sure to get him back here" Of course we soon had more dates scheduled. That joyous scenario does not occur these days.
While there are many reasons why you, or any of us, are sometimes not called back, now days it's usually "all about the money" It's so unfortunate, because we all know how passionate most of the residents are about the music we bring them. Sadly, corporation doesn't know, or doesn't care.
Good luck,
