Fluxblog posts a track from the new Junior Senior record: http://www.fluxblog.org/2005/08/its-hard-to-find-pearl-in-heart-of.html
I still need to listen to it some more, but my initial impression is that the album is solid even though it can't come close to touching the debut. How could it? They've gotten much better with production, but it's come at the expense of their trademark manic energy. Still, not bad.
