Jimmy Fallon's reaction to The Dirty Projectors' performance of "When the World Comes to an End" is exactly what I was thinking. "Yeaaas! How did you do that?!?" It's amazing how the girls just started this song off like a well-oiled music machine. It's like someone hit play and this three voiced instrument just up and went.
I was never really a huge fan of The Dirty Projectors' earlier work, but this seems to be their year. Bitte Orca has definitely grown on me. I believe "When the World Comes to an End" was originally a collaboration with Bjork performed at Housing Works back in May. Dave Longstreth has honed his skills at making amazing vocal arrangements (such as above) and showing off Amber Coffman, Angel Deradoorian, and Haley Dekle's capabilities as individual singers as well as their collective efforts to blend as one instrument.
I also love the Dirty Projectors for the way they play with time. "Useful Chamber" is easily my favorite track on the album. The best part for me comes in around 3:10 with that well-oiled vocal machine moving from pure tone voice to the head voice. Moving from one section to another comes off so effortless for The Dirty Projectors and the 6 minute + song wouldn't be complete without all of them.
