What happened in the culture was swift, also visceral and surprisingly long lasting. The Matthews band lost a little bit of its environmental luster. This group whose Ben & Jerry’s flavor donated proceeds to combat climate change — in the early 2000s — was now also and seemingly forever an Internet punchline about attempted river pollution gone awry. It also had to admit that it toured in five separate buses, and the culprit vehicle was the one used by band violinist Boyd Tinsley. (Side note: A sign you’ve made it as a rock band is when you not only have a full-time violinist, but that violinist has his own tour bus.)
