I liked Lissie's song, haven't heard anything else from her but I thought it was quite good and she has a great stage presence - it was one of the more compelling performances because it seemed more like it could be "real" and not just lip-synched etc (insert Club Silencio reference here).
I voted for Sharon Van Etten - it's an okay song, not outright bad per se, but it's a bit draggy and a bit whiny almost. It's aiming at an emotional resonance which makes sense given the highly charged content of Part 6, but the whole tone of her voice and the music just doesn't work for Twin Peaks for me, it's a little too ordinary. Which I'd actually say is somewhat true for Lissie as well but not to the same extent - I'd guess that most vote Lissie the worst because maybe she doesn't have much of a TP vibe to her music, not that song anyway. That's the only thing I could say against it really, otherwise it was good stuff. But Sharon's tune was kinda a slog.
Otherwise, I actually would vote James Marshall's lowly as it was just the same exact track as Episode 9 and it didn't do enough new things with it to feel like much more of a nostalgia-fest... it was fun and all the first viewing, when he was announced and all, but it's a bit repetitive as a song to say the least and so for a Roadhouse performance it falls short - despite the thing with Renee which was at least some kind of engaging thread. I'd prefer though if we got a bit more backstory on James in the last 25 years, perhaps confirming that Donna had died after an accident on his bike, and he's been a broken and guilt-filled shell of his former self since then, or whatever.. that would give this performance much much more power. As is, it's just a bit empty. But it was moving simply to see the older James's face and his newly shaved head and to contemplate that passage of time.
I would hardly vote it worst but I will say Rebekah Del Rio's autotune made her song more frustrating than it should be. It's a long song and a bit samey or repetitive already - though otherwise quite gorgeous - so having that autotune effect where it sounds like a robot is singing every 30 seconds.... didn't help.
Loved Trouble, Cactus Blossoms, Chromatics, and NIN to an extent. Au Revoir Simone were good. Lukewarm on Vedder, The Veils, and Cruise - look, if we're evaluating these as performances then the whole scene of The World Spins just was disappointing. Yes it was cool the way it cut in at the end from that devastating moment in the forest, yes it was lit nicely and Lynch wisely didn't cut from the wide shot of the band to any Roadhouse activity or crowd shots, and of course it's an absolutely incredible song, no doubt about that. BUT, it was already put to perfect use in the Roadhouse in Episode 14. And so I can only associate the song with that amazing sequence when I hear it. I suspect many others are similar. So it's unfortunate to bring it back and try to make it work for a whole other scene and context when it's already so solidly rooted in that ending of Maddie's murder, Bobby looking lost, Donna sobbing, "I'm so sorry," etc. Plus, it was just a tiny snippet of the song. Why? I understand Cruise's anger, especially for her to only get this bit of a song while everyone else gets an entire song played. So why use that bit at all then? It worked for me as a tonal placeholder between 17 and 18 and a way of setting a mood, but it still is a big disappointment that this is all Cruise was given to do.
