You guys probably haven't thought about some of these huge bands in business terms. View the band as a business, the band members are employees, on top of other staff (agent, band manager, road manager, lawyer, tech people etc) who all need to get paid. Bands like Unearth can't play shows they want to, they play shows they are booked to play by their agent. The band might not care about playing a hall show or a fest for less money, but all the people who make their living off the band do care because thats their bread and butter. They have legal contracts with all these people that they are obligated to follow, so showing their roots has nothing to do with this at all and you are all fools if you think thats the case.
