The New Yorker had a review of a band named Arcade Fire several weeks ago. Their weird high energy craziness reminds me of a band from the late 70s named Television--the band David Byrne and the Talking Heads wanted to be.
My son Nathan and I just listened to several Arcade Fire songs followed by several YouTube videos of live sets. Nate's decided the band is made up of musicians like Andrew Dionne who got tired of making snap-crackle-pop-bang classical music and switched to rock. For a taste of their music check out this video.
And if you really want to catch them in their glory, check out the drummer/tambourinist in this video. Unprompted, Nate echoed Tim Varner's comment when he first showed me the video: "He looks just the kid in Napoleon Dynamite." (Finally, ignore David Bowie. Nate took one look at him and said, "He looks like he's had too much Botox.")
