Jazz took too much discipline. You have to come in at the right place which is different than me singing the blues where I can sing 'Oh baby ' if there's a pause in the melody. With jazz you better leave that space open or put in something real cool.
Personal technology has given us the freedom of being able to do whatever we want - and in the case of celebrities and athletes whomever they want. But it can also serve as a humiliation jetpack.
