She put out an album a little while back of Tom Waits covers. That mad scientist's abortion, I am definitely not recommending.
I am recommending that you check out two of the songs she does on an album she recorded with Pete Yorn in 2006, but that was released this year : Relator and Blackie's Dead.
They're getting tons of radio play on KCRW. Also, they were on live today, so you can probably hear/see that performance on KCRW's site in the Morning Becomes Eclectic archives.
The tracks are fun, poppy, alt-country-ish and sing-a-long-able. They'll stick in your head. As for your opinion of ScarJo, I'm not sure what this will do one way or the other.
