Her fifth studio album What We Saw From the Cheap Seats, released earlier this year, captures that collision of inspirations beautifully, with many of the tracks recorded live with Spektor playing piano and singing simultaneously, with further wide-ranging instrumentation and experimentation added over the top.
The songs were not all specifically written for this album however, as the prolific Spektor has 10 years' worth of songs waiting in the wings which haven't been recorded or released, just waiting to find a home on an album.
"There's a song I want to put on every album but for whatever reason it just doesn't feel right, so I'll wait until the next record and try again, and then wait until the next record and then try again. There are some songs that have been waiting for a really long time."
She's also hesitant to try to explain where the inspiration for her wide-ranging music comes from, or even the album title - it's not that she's inarticulate on the subject, just reluctant to colour her music with explanations.
"I always have the hardest time trying to talk about it, because I like to be conceptual but not necessarily definitive. I always prefer for as much of the art to stay free of my own definition as possible, I feel like it weighs it down.
"But I can tell you I was thinking of the title long before I ever started working on the record, and long before I knew what songs would be on there.
"It's not necessarily that I had a concept, it just felt right I guess."
Many have commented on her wonderful observational ability, and her lovely viewpoint that is somehow both childlike and wise, whether it's a quirkily barbed political comment, or during a deep love ballad. Spektor feels she has no particular goal or agenda when it comes to writing songs, the ideas simply arrive.
"You're not really trying or thinking, you're just being really open and doing what feels right. We're always thinking and shaping our thoughts, and I think you're constantly making art even when you're not doing it deliberately. You might think 'oh, I came up with that so fast', but for all you know you've been working on this for years and you just didn't realise.
"Slowly but surely little things get stuck to a little idea and it grows in your subconscious, until suddenly it's just there.
"In that way I don't really believe in wasted time so much anymore" she laughs.
"Or maybe it's just my convenient way of being lazy, I don't know!"
Lazy is not the right word, but she's certainly an artist from whom talent seems to simply flow, and she appears unconcerned about ever having writer's block - for a long time she wouldn't actually write her songs down as she was creating them, confident another one would soon arrive.
"I used to forget a lot of songs" she laughs, "but I got really lucky, because I play all of my songs live, like every song I've ever written, and there would always be people that would record my shows and put them online.
"I am so grateful to them because I honestly wouldn't have had the chance to work on a lot of the songs without those recordings".
So if you're there to see her perform at the Auckland Town Hall (with support from Only Son, aka Jack Dishel, who recently became her husband), feel free to whip out your camera and record a clip or two - Spektor could be very grateful when she wants to jog her memory for the next album.
