Durrett made her debut on her uncle's second record, West of Rome, playing violin "wherever [producer Michael Stipe] 'heard' violin" as Vic put it in the liner notes (her sister Mandi played cello). Allmusic credits her with "choir, chorus" on 1995's Is the Actor Happy? but I can't find her in the liner notes. I'm going to take a not-so-wild guess and say it was on "Betty Lonely", which is the kind of kudzu-tangled, southern-themed track that would be right in Durrett's musical wheelhouse.
"What Do You Mean?", from 2005's Ghetto Bells, utilizes Liz's talents in much the same, by multi-tracking the hell out of her ethereal vocals, but to even greater effect. The song's construction is a playful spin on call-and-response, and is also a sort of whimsical SAT-prep, with both Chesnutt and choral-Durrett providing indirect definitions for words they later reveal. Example:
Vic: Like a puppy on a trampoline
Choral-Liz: What do you mean?
Vic: Bewildered.
Choral-Liz: We heard you laughing
Vic: What do you mean?
Choral-Liz: Felicity
It's one of the highlights not only of Ghetto Bells, but probably Chesnutt's last several albums, not only for its idiosyncratic construction, but because of the gorgeous wash of instrumentation that sweeps over the song, making the most out of a crew of absolute pros that included Bill Frisell, Don Heffington, and Van Dyke Parks. Despite the puppies and trampolines, the song is not fluffy in the least. The arrangement is both melancholy and serene, Durrett's voice is layered into a choir of angels, and the song becomes (like Durrett's own body of work) much more than it seems at first.
The second set of Vic-Liz interplay goes like this:
Vic: Like a salmon headed up a stream
Liz: What do you mean?
Vic: Ambivalent.
Liz: We heard you whistling
Vic: What do you mean?
Liz: Contentment.
Vic's lines in both verses offer visual images and end in adjectives that describe his mood. Liz's lines describe sounds and end with nouns. I'm not sure how much this needs to be unpacked, but the consistency is interesting at least. It also seems as if the Durrett choir's purpose is to call Chesnutt's bluff, essentially saying, "You can't fool us, we know there's happiness in you."
In the poet W.D. Snodgrass's lecture-essay "Tact and the Poet's Force" (which I will no doubt reference again and again on this blog), he talks briefly about how people generally react to others' declarations of feeling with some suspicion. For example, a friend telling you that they're having the best day of their life is way less convincing than the body language and other indirect signals that would move toward proving that exaggerated statement. That's kind of how "What Do You Mean?" works: you can say you're feeling ambivalent or bewildered, but I heard you laughing and whistling, so you're showing me something different. Vic's whole catalog of songs is full of that push and pull, between songs that are outwardly dark and tragic, but contain bits of mirth, to songs that are buoyant and silly while putting forth brutal truths. The answer to the question, "What do you mean?" is then, "Life is complicated." People are complicated.
If the emphasis is placed on the word "you", and the question is "What do you mean?", then the song's answer is that we're a collection of moods and feelings that shapeshift into each other. The song's bridge goes:
Vic: It is a vibration, it moves in a wave
Liz: You are a surfer on that clarion tone
Vic: I hope so
Liz: We know so
Vic: I hope so
So moment to moment each day, we hope to be surfers, to navigate the crests and drops of our moods with smoothness, to not get stuck, to stay afloat, all of the metaphors I have no desire to try and think up right now because I'm not a surfer.
