No, you're onto something. I'm pretty sure that, barring whatever talent may be inherent to some of the bands above, if we dropped the entire listed bill into a volcano, it would still be an overall boon to music. And I say that as someone who normally hates comments made solely to inflame.
The state of popular music/groups in the scene is just dismal at this point.
It means they had to find a way to perform without being required to actually carry a tune.
