Bands You Would Like To See But Never Will/Doubt You Will See

I wanna see Bloodbath,Vomitory,Cannibal Corpse,Korpiklaani,Finntroll,Vader,Black Label Society etc lolz
 
I'd also quite like to see the Megadeth, Slayer, Machinehead or other concoction gig things, but they seem to be everywhere but the UK, apart from priest feast which i missed.
 
Im going to see Slayer already even though i'm not that bothered cause I only really like 2 albums.
Megadeth I WILL SEE!!!! Machine Head I only have 1 album and not paying £30 if i only know one
I meant them altogether though cause that would be cool.
