REQUIREMENTS:

• Your band must have some degree of technical talent, but not much.
• You have to be able to have satisfying levels of bass in your mixing/production

STEPS:

• Pick any Metallica song from the first four albums
• Increase the tempo slightly
• Make absolutely sure that the drums are tight, as well as denser/heavier than the original
• Make the guitars a little fuzzier than the original
• If you're covering a song from AJFA or MoP, cut out whichever parts you find boring or redundant
• While the bass itself doesn't need to be audible, the bass END does

Bands who have successfully done this:
Between the Buried and Me
Trivium
Johntegrity is the Bastard
Devolved (in all facets except the bass end)
