This truly is amazing. I mean that, I'm not saying it sarcastically.
Is the music amazing? Not by any means. But these guys are serious. They truly believe in what they are doing. Granted, it is on YouTube, but these guys are not doing it for the attention. They are not trying to be "ironic" (see:
Rickrolling,
Ironic Mustache). Their heart is in it, and that's more than can be said for a lot of musically acts these day.
