One of the really cool things about the Internet is that I run across music that I would have never heard in a million years in the absence of the net.
In this case, I was actually searching for some answers relating to a gravitational matter when I ran across a blog called, "The Reference Frame", belonging to Luboš Motl in the Czech Republic; and in it he had a clip from the 2001 Czech retro movie Rebelové in which Zuzana Norisová performs a Czech rendition of Sugartown.
In some of her other music I've found, she reminds me very much of Joni Mitchell but smoother, but her voice is very emotional, has an extreme range and is just velvety smooth. Particularly, locate a piece called, "Mary, anyone could be wrong."
