Yes I watched that documentary and it was really enjoyable.Agree with your remarks both on her looks and her music.
Hounds of love is my favourite pop/rock CD of all time. I thought Aerial was an amazing comeback, but 50 Words for Snow made less of an impression on me.
I recommend the BBC4 documentary about her on YouTube (4 links, see here).
Aerial was an amazing comeback and I agree it was a better album than 50 words. She specialises in making comebacks with the amount of time it takes her to get a record out nowadays. I was really sorry not to see her live recently when she did a few dates in London. She probably won't do any more as it was her first live dates since the 70's.
Hounds of Love is one of my favourites - I'd probably put it very near the top. Hello Earth continues to send tingles down my spine 30 years after first hearing it and I can't say that about many pieces of music.
