I thought the same thing, but there's another video (http://www.youtube.com/watch?v=t13ulrSXaHo) where you get a better sense of how it all sounded together. I personally enjoyed this performance from the other video, but that's coming from someone who enjoys the album.
I was personally a bit disappointed by the sound of the piano throughout the song, it just seemed like a needless change to the music. Unless it just came out weird on both videos I've seen.
Don't think it sounded any better tbh :/ I like Piano Wire, but live it sounds terrible for the most part, and the rest of the album didn't really do anything for me.
I think the coolest part of the show was finding out that Strandberg's involved. Definitely didn't see that coming, never thought he'd mesh with this kind of crowd, but I'm glad his talent is being recognized outside of the Goddamn Band.
