Alison has already worked with such artists as Sting, Brad Paisley, James Taylor, Dolly Parton and Alan Jackson. «I think of it as a window into some other world», - she described her work with Robert Plant and other musicians.

Plant himself said that his vision on the album was a little more lightweight – but «Alison wanted something more serious, with more color and shade». He added that they both had new experience – Plant had to sing in a manner he never tried before, and Krauss had to sing songs «that didn't always fit her».
