Kate Tucker & the Sons of Sweden

I originally came across this excellent Nashville group on a mix by Charlie Lowell of Jars of Clay (who, it turns out, has a taste for electropop music which is very similar to mine).  Since the recent demise of grooveshark, I had a hard time finding any of their music to listen to for free, but I found their album on rdio, and I must say it's quite good.  I think you can also listen to most of their stuff on soundcloud site.  I particularly recommend the song "Hangover", it's so awesome.  I love the style of the music, with orchestral and highly melodic instrumentation behind the girl's crazy ethereal voice.  Presumably that's Kate Tucker.  In any case, you should definitely listen to their one album "The Shape the Color the Feel".
