It's hard to really say any one album strongly outshines another. They are a very solid, consistent band. Their latest, Seven Seals would be a great place to start, it's a nice balance between their earlier and later styles(a VERY, VERY subtle difference here). Then grab Jaws of Death and Nuclear Fire(in that order) from the back catalog. Funny I say this though, cuz my two favorite songs from them are off Devil's Ground. Metal Is Forever and The Healer. Saw 'em at BWBK festival and cannot wait to see them again. Very awesome live!
