This thread is absolutely terrific, thank you, but my bank account says "not so much".
+1 @doni for Molly Tuttle who I have also recently discovered.
@dz13 nice list but if you are going to mention Shirley Manson you better ad Chrissie Hynde to that list.
Now I am not going to go out on limb say the bond and comradeship of the three artist I would like to add to the list approaches the bond that did clearly exist between Linda, Emmy, and Dolly. But Marissa Nadler, Angel Olsen, and Sharon Van Etten do appear on one another albums occasionally, have been on tour together at one time or another, and generally seem to be credited with being at the top of the Indie scene right now. Plus there does seem to be a strong appreciation for one another’s musical direction that is evident after listening to entire catalog of each artist.
