Every one of her albums seems like a subwoofer demo disc. I'm listening to Surfacing at the moment, and every track turns the sofa into a massage chair. This album also has a very subtle (and unusual, these days) upright bass played with a bow on most tracks. It's a good test of your system's resolution to see if you can follow the bass line continuously through the track. The lap steel is cool too on the Witness track. Very nicely done pop music. Are there any other artists so into bass?
