I know it hurts you, but new metallica has no growls (hetfield), and musically even though they are good, they cannot go back to the old era
in all honesty, lamb of god is the better live performer. hands down... though i don't listen to them.
too hard to choose.. :D BOTH
In my opinion Lamb of God are way ahead live and I'm not even their biggest fan but they are incredible live. Great drummer which really adds to the live energy whereas Metallica have....well....Lars!
Lamb of God are way more technical and complex and interesting.
metallica bro... the riffs...so delicious...:D
