That would be the best combination for me. MY TWO FAVE BANDS!!! I saw the GGD twice on their tour this summer (would have been three if they came back to FL on the fall leg of the tour). They are incredible live. However, I know that both bands are not really fans of each other. Both have made comments about the other.....Plus, usually, not always, but usually, bands have an opening act that is on the same label as them to promote that other band. But if this is true though.....OH MY GOD!!!!!!!
