Every now and again my buddy Brian -- referred to through the years here as Pop Warner -- opens up a door to the coolest scenes. Brian works for Warner Music; he is sort of the company’s liaison with iTunes. I say “sort of” because his job is actually quite a bit more complicated than the title and over time he’s offered me countless insights and fantastic access into the music world. In return, I tell him the Cubs teams he grew up with were generally terrible. It’s probably not an even trade.
