I was listening to Bjork as the guest DJ on All Songs Considered. She has an esthetic I can appreciate ... blending electronic and natural sounds in her music. She is using a gestural control instrument from Reactable on her Voltaic tour that can be seen in this video from "Later with Jools Holland".
To get a feel for the Voltaic live show, here is a video of "Pluto" from the Paris show.
Just ordered a copy of Volta...looking forward to the listen.
