The Lores will be fine for that type of music, but even better with your live rock recordings. I don't listen to MEtallica per say anymore, but I do listen to mostly rock and some harder stuff. The Lores a definitely not too soft and certainly not going to be bright either. They are very neutral but designed to sound like live music, opposed to a hi Fi sound... If that makes sense. Agood tube amp 10+ watts and you should be a happy guy.
