I can't imagine what it would be like to be a busker, singing and playing your heart out and having people walk by without glance, let alone stopping to appreciate your talent, maybe give you some money.  I got to thinking about this when I was listening to a Scottish artist I recently came across by the name of Rachel Sermanni.  Following her videos around Youtube I found one of her singing "Ae Fond Kiss" written by Robert Burns, for something called The Mahogany Sessions (if you don't know about The Mahogany Sessions you should check them out, brilliant new artists preforming live and unplugged in some unique and beautiful locations).  Sermanni's performance of "Ae Fond Kiss"  is soft and haunting, her voice fresh and her manner seeming innocent.  There is a captivating quality to her singing style and it is hard for me to understand that people can walk right past, upon hearing it, and not feel the urge to stop.  You should also check out her own song "The Fog" which I am currently listening to on repeat!
