She's an interesting case. So much Fi in her! All those pained faces, giddy gliggles, etc. But her fluid movements and overall rhythm of her body and eyes suggest P-lead imo.
I think she might be what an Si-heavy NeFi look like xD Omg, all those scrunches... they made me wonder if she could even be SiTe, but overall... her energy and she way her psyche moves seems more Ne-lead. In the second video I see more momentum (lots of it) than in the first video.
(lol, wasn't there any other talk show in the US at that time for her to be interviewed? All videos of her being interviewed are with the same interviewer, in the same show xD)
Yeah, NeFi seems to make sense. She reminds me a bit of Florence Welch, actually, although Welch might have been influenced directly by Janis Joplin. It'd be interesting to observe the types in the same lines of work to see the commonalities between them.
