Now I may have a heard a song by a few of the others but outside of that these are the artists i'm most familiar with. I was just reading the other thread and this guy said he knows 75 percnet of the bands and i'm at the complete opposit end of the spectrum, I go to this thing knowing like 20 percent of the bands if that and love having the ability to check out a few new bands and the others I must see.
