THE GUARDIANS: Heavy Metal - The Modern Era

To complete this challenge, you need to review each and every release on the list below. Note that ratings are not considered reviews. Also note that reviews do not have to be essays, but they must include personal views based on personal experience. If anyone's considering cheating, please realise that you'll only be ruining the Metal Academy experience for yourself.

Completion of any Clan Challenge will "lock in" that clan for that Metal Academy attendee. Note that completing any Clan Challenge will achieve this, so you don't have to complete them all for any particular clan. Once you've locked in all three of your starting clans, you can lock in a fourth one to add that clan to your profile. That's right, you can earn yourself a fourth clan!

I've purposely chosen the big albums when putting these challenges together as I didn't want to make it too hard. That being said, there are some lesser known releases in each of them. Now go educate yourself and most importantly, enjoy some great metal!
