Lou Rawls is my favorite male vocalist "ever", and I find that easy to say without restrictions.
Rok, you know how I am about the "Jazz Classics"; you got to stick to the script. Well, Dianne Reeves broke all the rules on "Summertime", but she did it in such a spectacular way, that not only is she forgiven, but she has my permission to break the rules anytime she feels like it.
