I love Children of Bodom, they are so great live!
Amon Amarth is definately worth a check!
Tarot is a good band too, as well as Blind Guardian and Hammerfall, and personally I enjoy Finntroll.
If you like Nightwish, check out Leaves' Eyes as well.
Alright sir, sure I'll have another one it's early.
Three olives, shake it up, I like it dirty.
Tequila for my friend it makes her flirty.
