I adore the "Stories.." album, but on my stereo I did have the same problem with the production.. It sounds perfect on my mp3 though, so it doesn't put me off the alb in general. I love Thom Yorke's contribution.
I haven't got the "Desert Sessions." I know she features (vocally, and in some cases playing various instruments) on the tracks "A Girl Like Me", "Powdered Wig Machine", "Crawl Home", "I Wanna Make It Wit Chu", "There Will Never Be A Better Time", and "Dead In Love." Not sure about the others though. The album has been on my to-get list for a while.. I've heard "Powdered Wig Machine" and like it a lot.
