I understand that for you economics and culture are inextricably intertwined. This saddens me. I don't perceive culture the same way. Whether or not something achieves economic success and builds a large audience has absolutely nothing to do with my enjoyment of it. There are musicians whose work I enjoy far more than either of the two bands you mentioned. There are writers, musicians, filmmakers, gardeners, bakers, cooks, winemakers, sculptors, architects, composers, poets, actors, singers, etc etc who will NEVER become household names, but are valid and important elements in the cultural fabric. The fame and/or success someone achieves has NOTHING to do with the value of their cultural production (for me).
