If for some reason Candlemass were unable to come next year, would anyone be willing to throw their support to Memory Garden? They've often been referred to as a "modern-day" Candlemass... they're supposed to have a new album out before next year (after a 7 year hiatus), and considering how well SA went over this year, I think they'd make a great doom band for next year... plus, they've never played the States, as far as I know.
Or, maybe we could have BOTH bands
