I have been a big Kate fan since the late Seventies - and, being a woman myself, it certainly wasn't because of her looks
. However, I would not call her a 'proggier Madonna' - this does both her music and her voice a huge disservice. Kate is a completely different personality than Madonna, and she is definitely much more talented as a singer (even though her voice may be an acquired taste). As regards her albums, even though Hounds of Love is much more cohesive as an effort, my favourite from hers is probably
The Dreaming - "Pull Out the Pin" has some of the most haunting lyrics I have heard, and the music is not bad either.
The Red Shoes, on the other hand, was a disappointment, even though (as Alan pointed out) there are some good songs to be found there too.
