Thought from last night...
So there's something religious, something etherial about hearing amazingly good, breakthrough, original music live. Sure, the Decemberists are great, but not like Radiohead or Wilco.
Say what you will about Pitchfork-- I find some of their reviews questionable, but when they give something a 10, I almost always agree. And when I hear a 10 live, I realize what bliss is.
