Jenny Lewis is the lead singer of Rilo Kiley, a rock/country/pop act that is pretty great (you can watch the video for the kind of upbeat "Portions for Foxes" here). Her voice has an odd quality to it, where it sounds like she might cry - just a little - at any moment. So, she's done a solo(ish?) album called "Rabbit Fur Coat," which is much more country and much slower moving than most Rilo Kiley stuff (or the recent stuff, anyway). And she went on KCRW's Morning Becomes Eclectic to promote it. And KCRW put it (like all other performances) up on their site here.
The performance is a little uneven (maybe it's the album), but it's always pretty and her voice holds it all together.
