A fan legend is one of those people who's been listening to the band forever. They might have even listened to them before they were out, when they were still myspace bands or only known about in the area they originated. They aren't first jumpers
who normally go after the good music and turn them mainstream or media, but they're the true, real fans who've been around forever.
