As powerful as that song is in the movie, I think her video for it is even better.
To me, Hounds Of Love is an essential album, and it may be the one where her vision was most fully realized. That said, The Sensual World is not far behind. This song is one of my favorites from that album - the use of Trio Bulgarka is outstanding (although there were rumors that Kate learned to sing like them and did some of those vocals on the album herself), but the drum fill at 2:05 grabbed me from day one and has never let go. I've ripped that off several times.
