You’ve probably heard the theory, popularized by Malcolm Gladwell, that there’s a magic threshold of 10,000 hours of cumulative practice that fosters excellence and success among artists, athletes and other purveyors of a craft. So maybe it’s not as true as social scientists once thought, but it is certainly intuitive that if a band was able to play live for people nearly every day for up to ten hours at a time, over years, that they’d grow tighter, sharper and more attuned to one another. It sure feels true with the Po’ Ramblin’ Boys.
