There wasn't that kind of clarity from a musical position on Queer. He threw out lots of different things that were kind of riddles to solve, but, eventually, what we decided on was leaning into Burroughs and the idea of the cut-up technique and using samplers. It felt like an organic way to tell the story musically.

Reznor: I just found some notes from a call with Luca. So I'll read [them to] you. Here was our directions: "Love could feel like dread—Stockhausen. Lee towards lover—engulfing, overwhelming, an uncompromising approach. He's a broken, lonely man—unknown reciprocation, unsure throughout, but still beautiful. I like the scale of an orchestra—bipolar. Make the score bipolar. Burroughs was like this, from Old America, but contemporary—the score should be like that. Maybe electronic element—Ayahuasca." Okay—go write a score.

the original cut was significantly longer, at least an hour longer than what's in theaters now. And a lot of what was taken out was a more surreal element that was exciting and alters the way the film feels quite a bit. When a lot of that got removed, it was hard for us to understand what the film became, because it shifted the tone of it quite a bit in certain ways.

It became disorienting at times to also quantify the impact the whole film has. You know what I mean? We're watching three-minute chunks, a week of this three-minute and then a week of that seven-minute segment, assuming it sits atop the scaffolding that got us there and leads to what's happening.

sometimes, when you start taking those pieces out, it becomes harder to understand. What you're working on is now affected because it doesn't have that stuff you know is there because you watched it, but it's not there. That's the part of filmmaking that I find tricky. We've experienced it with [David] Fincher as well on some things. To be able, as a director, to remain objective with that many moving parts, that's what feels... When people have said, “Do you ever think about directing?”—it's like, I've thought about how I know I couldn't do it. I thought about, “Well, I'd like to do it,” but it's like, the ability to be able to remain objective about so many things, that feels daunting to me. And as composers we feel like we're able to microscope in to get really close up on things.

It’s Kali Uchis describing falling in love like melting like ice cream. It’s St. Teresa’s ecstasy. It’s why 18th-century German poet Ludwig Uhland said that waking up buried in his lover’s arms is like dying from love’s bliss because he “saw Heaven in her eyes.” Heaven is commonly used to describe this feeling because falling in love is like dying: Both death and falling in love are about losing a grip on reality, leaving this world and entering the ethereal. Like death, we describe a soul in love as being escorted away by angels to a better place. It’s why Cupid has wings—so he can take us from over here to over there.

Yet, when you try to articulate the deepest of your desires, you can’t find a name for it. It’s like that marvellous ache you feel when you see the Milky Way spilled across the sky—it draws you in and makes you long for more of it. This longing has the shape of the infinite. I know a love song is good when I don’t know if they’re singing about a lover or God.

Love, in its purest form, feels like mysticism, like being absorbed into something that wants you to be part of it as much as you want to join it. Some might call it a longing for happiness, but it is so much deeper. Here’s what I mean by mysticism: it’s something that grows your wonder instead of trying to solve it. “Life is not a problem to be solved, but a reality to be experienced.”

It’s like watching fire—something that constantly moves without going anywhere. It’s “alive” in its own way. Like how God speaks through a bush that burns but is not consumed, something ineffable about music—the way it decorates time like art decorates space—speaks to us.

Guadagnino brought them Challengers, which will be released this month. Reznor said, “He started us down a path, saying, ‘What if it was very loud techno music through the whole film?’ ” (This is exactly what it turned out to be.)“I wish I had his notes,” Ross said of Guadagnino. “His notes were so fucking funny on what each piece was meant to do.”“Oh, yeah,” Reznor said. “ ‘Unending homoerotic desire.’ It was all a variation on those three words.”
