Who are your three favorite female singers?


I have favorites, but would like to hear from others.  Thanks

Off the top of my head...
Janis Joplin
Elly Ameling
Ella Fitzgerald
Edited to deal with this website's damnably clumsy posting regimen.

I had the pleasure of seeing Heart live and the Wilson sisters were in their prime and just nailed the performance.  It was in an acoustically great performing arts center at a Big Ten school...quite a night.  It was some time back, as their warm up/lead in act was The Little River Band. One of the best live events I have seen. 
Perhaps my favorite live events were the three times I saw Jackson Browne.
