So, he posted this Youtube some weeks ago.  It was Kenny Drew Jr. Playing left hand only.  
You realize how important it is after you lost it.  Because of this injury, I couldn't use my right hand.  I finally realized that I only think about my right hand.  My left hand can't do even a half of what my right hand can do.  
So, Kenny Drew Jr. was truly amazing.  It must take a lot of guts to do it..... and I wonder if I can play left hand only like him in this lifetime.
Too sad that he passed away such an early age.  Rest in peace.
