I haven't been obsessed by a record like this in a long time.
I joined emusic recently (it's kind of a joke) but I was able to download "Armchair Apocrypha" by Andrew Bird and I can't quit listening to it.
It has a Sufjan Stevens feel (with whistling in almost every song), it's orchestral, but it also has a solid base of roots rock song structure.
It's kind of blowing my mind. I love it.
For one of the more palatable songs, "Heretic," click here.
