I thoroughly enjoyed listening to this CD while walking to work. There are some very powerful songs and performances by some of my favourites artists such as Jonny Lang (lie to me), Christine Aguilera (love here jazz/pop-sing-improve) and not to forget Lennox, Sting or John Mayer....powerful. It's is also great to listen to the piano playing by Herbie Hancock which is so amazingly perfect and yet totally improvised. How does he do it?
