Query: Hammerfall's Best!

I think this album is a masterpiece! There are great vocals and stunning music. I just found out about this band a couple weeks ago, but I already love them. They remind me of the music by Iced Earth and Jag Panzer. If you like those bands you should by this album. Hammerfall is an excellent band that you should hear for yourself.
