If you haven't heard or seen the episode of Q with Billy Bob Thorton acting like a child not getting his way than you must be living under a rock.
Either way here it is:
The performance that he walks off from is not posted because of legal issues (that will probably never be resolved). Here is another performance of his 'Cosmic Country Music'.
Now I just wanted to compare this to a Canadian band that is both far more talented and far more experienced despite being quite a bit younger. The Sadies have been doing this type of Alt-Country for quite some time and are pretty much a Canadian indie-rock fixture. They even have their own label. Here is an example of the stuff they do. I couldn't find a really good example but this one will have to do:
So when Billy Bob tries to say that he is the only one doing this and starts comparing himself to Tom Petty and says that Canada doesn't have anything as good as his band well I beg to differ. For such a small spread out population we have an incredible music scene. Sure we don't get up and through bottles and chairs at each other but we would rather hear the music and check out the talent which is something that apparently you don't do at a Boxmasters show.
