I am a huge Kate Bush fan, especially of any of the recordings she did in the eighties and earlier. That pretty much only eliminates The Red Shoes, which I never learned to appreciate (With the notable exception of "Moments of Pleasure", which is simply fantastic).  I used to be an avid follower of rec.music.gaffa, but now I only browse it when I have time. I don't participate in the trivia so much anymore, but I listen to most of my Kate CDs each week.

If you'd like to learn more about Kate, I suggest that you visit Gaffaweb, a very complete site with tons of interviews, pictures and reference materials.  I think of Gaffaweb as either the authoritative work, or the best source on most thinks Kate.  Also, the Kate Bush lyrics, links and images site has a good set of links along with brief descriptions of what you can expect.  And since their site is a little bit smaller and only includes the important stuff, it's easier to find what you're looking for if they have it.  If you're looking for current Kate News, may I suggest you visit Seán Twomey's Kate Bush News & Information site.   It has good current news about her upcoming album!
