I don't think it's quite accurate to call Wilco underrated because they've had some serious critical acclaim, none more so than their album that many critics viewed as their masterpiece, 2002's Yankee Hotel Foxtrot.

But they are definitely under appreciated. I really don't know many friends my age that love Wilco. In case you'd like a primer on them, check out my "Best Of"

For some reason, they seemed to only have really stuck with a previous generation. Yet they still make great music. Their leader, Jeff Tweedy, just released a phenomenal and subdued acoustic album of some of Wilco's great tracks. I liken his voice to Bob Dylan. It's not good but that's exactly why it's so great. His soul is represented in his vocals, it's a scarred beauty.

"One Wing" was not included on this album (no idea why either because this is such a cool interpretation of it), but Tweedy performed it at music fest, Pickathon. A remarkable performance, even more so as it highlights his penchant for lyrics:

We once belonged to a bird
Who cast his shadow on this world
You were a blessing and I was a curse
I did my best not to make things worse for you
It isn't true, I always knew this would be our fate
This is what happens when we separate
This happens to all dead weight, eventually
We may as well be made of stone
We can't be flown

One wing will never fly
Neither yours nor mine
I fear we can only wave goodbye
