I was listening to her GHV2 album today and it's amazing how much electronica is on it, even though you would hardly classify her as an electronic artist. To top it all I believe her latest single is done in collaboration with electronica-princess M.I.A., who I instantly recognised.
Here's one of my Mad (sic.) faves anyway, the William Orbit produced Ray of Light from the 1998 album of the same name.
