The Bush Branch; Pistils without Stamens?

[<gearnoise@VNET.IBM.COM>]

I was recently looking at local Chapel Hill, North Carolina singer-
song writer Heather Russell's website, and came across this quote from
a review of one of her performances (Hope you don't mind, Heather):

".... a branch of rock music pretty much invented by <Kate> Bush
 and plied solely by women. Like Bush and Siberry ....."

Thinking about it, that appears to be a true statement.  With my rather
limited exposure to the music scene, I cannot think of a male singer -
songwriter that would belong in the same genre as Kate Bush or Jane
Siberry or Sarah MacLaghlin.

Any thoughts as to why that is so?
Or does someone know of a male whom one might consider in the same
classification?

(by the way, Heather's website is http://www.freecloud.com/heather
 She has some .wav samples, but I can only look at text at the moment).
