i saw slipknot twice as well, once at ozzfest 2005 and at last year's mayhem fest. i've seen mudvayne twice, once at some small club in 2003 and at ozzfest 2005. i saw LoG back in april earlier this year and cannibal at this past mayhem
true that, x-voltage. i've been to Mayhemfest the last two years and both years were pretty awesome. i really hope lamb of god play there within the next 2-3 years, that would be off the charts. Bullet for my valentine being there instead of cannibal was a huge load of bullshit, i agree.
i recommend checking out MuDvAyNe. they're an acquired taste. they're not your typical metal band. they have an amazing bassist and one of the most technical drummers in metal. plus, the reason it would awesome to see them with slipknot after all these years together since they both kind of came out around the same time and to see them live on the same tour and playing much more evolved music then what they started out doing would be almost a once-in-a-lifetime opportunity
