Tribute bands are one thing. Posers exist in all genres of music. I saw one of those local sorts of rockabilly bands. A guy I know was playing guitar for them shortly. Although there was a promise of great money in Europe, where he was told "anything American" sells like crazy, it turned out to be a bust. The leader of the band wasn't all that good to be calling the shots. Bands that go to that level of control are either THAT good, or are really just prolonging their failure, and passing the blame on to "nobody gets it".
