"Star Witness", by Neko Case, from the album "Fox Confessor Brings The Flood". Which has been around for a while, but for unexplainable reasons achieved maximum impact as it shuffled to the top of the iPod pack, while I was travelling home on the bus, in the dark, with the lights of Canberra appearing and disappearing around me. Neko Case may not have the most mellifluous voice going, but it is perfectly suited to the kind of country slant she gives the songs on this album. It is the kind of voice that picks you up and pins you to the wall. In a good way.
(There is another song on the album called "Margaret vs Pauline" which reminds me of work, where Margaret and Pauline have adjoining offices, although I have never seen any evidence of the use of "vs".)
