Can you feel it

 

What Janis did is actually very dangerous.  It can also be known as "all out abandon", and with emotions you need someone to catch you before you fall in too deep.  Materialism (entertainment business) is very imperfect, and despair is imminent when you invest your emotions in it.  When it comes to singing though, there's no other way to do it.  You have to give all your heart, or be mediocre.
