Marianne Faithfull
Dusty Springfield
Kate Bush
Petula Clark

1) Dusty Springfield- DUSTY IN MEMPHIS is great.
2) Petula Clark- A couple really nice pop tunes.
3) Marianne Faithful- Not terribly familiar with her but I've liked what I've heard.
4) Kate Bush- Haven't really been that thrilled with her output save "Running Up that Hill" and "This Woman's Work".

I love 1 & 2.

I only really know Kate Bush, and I like her enough. The others are undoubtedly talented, but I don't really have much of an urge to get into them any time soon. To be honest, I have so many huge gaps in my catalogue, and I'd probably first focus on artists like Billie Holiday, Nina Simone and the like. I know I'm the one missing out.

That said, Annie Lennox owns all.
