Jazz

A day I have done absolutely nothing besides eat and sleep - we have a saying in Portuguese about lazy guys: "He is just an eat-and-sleep guy". In my case, I thought it was necessary, I am feeling much better.
This is a book it was just delivered - a guide to know more about this fascinating music. One of the first things I learned was that, at the beginning, 100 years ago, it was written "jass" and not "jazz".
