So let’s get one thing straight. I am not a 20-something hipster tapping in to live twitter feeds from garage bands in Prague. I am not an old-school rocker with high off-road mileage and a septum tattered by blow. I am, like most of my middle-aged friends, a victim of an embarrassing epidemic that’s sweeping the nation. Musical Impotence.M.I. develops in three stages: 1) generalized musical apathy, leading to, 2) inability to get it up for live shows (yes, even the hot ones), resulting in, 3) complete ignorance of contemporary music culture.
