Despite all the technical improvements, it still boils down to a man or a woman and a microphone, playing music, sharing stories, talking about issues - communicating with an audience.
Again, as egotistical as I am, as self-centered as I am, and as much as I love strangers idolizing me, I find it very crass to be self-promoter in a way.
Sometimes I laugh with my parents, and sometimes I yell at them, and both are therapeutic.
