Earth has just been invaded by malicious, conceited aliens, if I may, from a galaxy far, far away. They have brought with them what they think to be the greatest band to grace this universe whom we will call Aythadis. Now they wish to enslave the human race and lord over Earth with a tyrannical regime, but the human’s love for music has caught their attention. So they decide to give us chance to redeem ourselves, and challenge Earth to an intergalactic battle of the bands to go up against Aythadis. The decision on which band should represent Earth needs to be made. Now before you give up Earth as lost, there is a catch: they have a time machine. Therefore, we get to choose any band from any era that we want to.
Here are my two cents on which five bands I would be comfortable resting Earth’s fate on, which year I’d pick them from, and the one “knockout track” that would defeat Aythadis.
