The one section of my interview with Sam Levey of Deficit Owls (the soon to be released premiere episode of Activist #MMT) that has nothing to do with Modern Monetary Theory. Before becoming an MMT-er, Sam's education and career was audio engineering. Specifically, he mixed live theater performances, something called "active mixing" or "line by line mixing." In order to avoid strange sounding problems (such as phase cancellation, which is when multiple microphones pick up the same sound at slightly different times), the mic of the person *about* to speak needed to turned up, and those *not* going to speak to be turned down. For every line of the entire show.
