Both articles were quite interesting, and complemented each other in a way.

I was finally able this morning to listen to the 28:18 "Do You Know How To Waltz" and I enjoyed it.

The short lyrics were sung just once:

One more dance
Before they take away the light
One more spin around the line
One more step
And then we'll turn and face the debt
One more reason to forget 

They have meaning for me; and the rest is soothing, meditative even.  I'm sure it would not have felt that way there, with everyone talking, drinking, texting, complaining. This is from one of the comments on the site:

"how shocking when a band chooses to play a song from one of their records at a show! I happen to find "do you know how to waltz" one of their most visceral and powerful songs--- the long droning crescendo, it's a beautiful thing. if your expectations of them as artists weren't met, well, maybe YOUR expectations are the things that are wrong. if you've followed Low from the beginning, you know that this is an element of their music."
