Wow. I'm amazed at some of this comments.
But I think the one that pretty much sums it up is ClaysTribe's "I refuse to listen".
Exactly. That's why you have no idea what you are talking about. There a lot of amazing bands on that list, which you might actually find once whoever it is that decides your opinions for you gets around to telling you so. Just because you haven't heard of a band is by no means a measure of their talent.
I have seen several of these bands live, and own albums by several more. Every band I know on this list is worth checking out.
If you happen to go to any of the "non-lame" American festivals do yourself a favor and check out some of these bands. Just about every major festival coming up includes at least one of them.
