Why Does It Shake?

Some songs announce their subject. This one opens with a bodily symptom and a nagging question, then spends its length declining to give a tidy answer. A tremor is the kind of thing you notice before you can explain it, and the title treats the shaking as a mystery worth sitting inside. That uncertainty is the song's whole posture, and it fits the record it lives on.

A quick note on provenance. The song appears on The Agent Intellect, the Detroit band's 2015 album for Hardly Art, and not on the later Relatives in Descent. The two records are linked, though, and the link is one of the more interesting things about this track.

Where it comes from

Protomartyr are a Detroit post-punk band fronted by Joe Casey, who delivers his lines in a weathered, half-spoken baritone over guitars that scrape and circle rather than soar. Casey has been candid that the band began as a way to fill his time, not as a career plan. He has described working as a doorman and at a nursing home, surrounded by friends in low-paying jobs, and starting a band instead of sitting in front of the television.^[2].

That grounding matters. The album is not the work of someone writing from a distance about decline. It comes from a person who spends his days among the people a city's economy tends to forget, and who then goes on stage to make sense of it, or to fail to, out loud.

An album about the mind under attack

Casey has explained that the album's title comes from an obscure Aristotelian idea, one he came across in a book on classical philosophy^[3]. He liked that philosophers have never agreed on what it means, which suited his sense that the mind is largely unknowable^[3]. In a separate interview he described the songs as concerned with how the mind works and how it can be attacked from both outside and inside, with the title serving as a metaphor for the mind itself^[2].

Read against that, a song about a body that will not stop trembling becomes a natural fit. The shake is a symptom without a diagnosis. It could be nerves, illness, cold, fear, or the low hum of living in a place that keeps getting worse. The song lets all of those readings coexist.

The wider album circles the same area from different directions. Casey has talked about faith and frustration, about the sense that people believe they understand the modern world far better than they do, and about the fear of aging and being nudged aside by younger generations^[3]. His source material was unusually strange: a sixteenth-century medical book on monstrous births that offered religious explanations for deformity, an online document about demons that corrupt computers, and memories of his years as an altar boy^[3]. Fear, the body and belief keep colliding.

Manufactured contentment

The most useful outside description of the song comes from NPR's review, which calls it churning and harshly textured, and hears the singer delivering a bleak assessment of modern society, pointing to manufactured contentment and its human cost^[1]. That is a good lens. The phrase suggests a world in which people are encouraged to feel fine, to consume their way to calm, while something underneath is plainly not fine.

Seen that way, the shaking is what the contentment fails to cover. A comfortable surface that trembles is a better image of a troubled society than a collapse would be, because it asks the listener to notice small signs before the damage is undeniable.

The same review places the whole record in a tradition of art-rock that undermines rock conventions while still hitting hard, and compares the band's approach to Pere Ubu's 1970s work^[1]. That comparison is apt for a band from an industrial American city that sounds as though it has been left out in the weather.

The city that keeps growing

One of the song's most lasting contributions is easy to miss. Casey has said that the imaginary city of Anacita first came up in a song called Born to Be Wine, as a place for a faded performer to live, and that he sang about it again in this one. By the time of the next album, he noted, the city had grown^[4].

That makes this track a kind of foundation stone. Anacita became the setting for one of the later album's singles, and it is a handy invention: a place that can stand in for any town where hope has been repackaged as a product. Casey has described the later record as being about the murkiness of truth, about legacy and family disappointment, about Detroit's economic decline, and about the good delusions people hold onto against hopelessness^[4]. Many of those concerns are already present in embryo here.

Critics have noted how the band's focus widened over time. Earlier records dealt with violence in their hometown, while later ones looked at its possible roots in religion, philosophy and biology^[5]. This song sits right at the hinge of that widening, with the physical, the philosophical and the civic all in one anxious frame.

Detroit without the postcards

It would be easy to read any Detroit band's darkness as a postcard of ruin. Protomartyr resist that. Casey's reference points are ordinary and specific: jobs, buildings, neighbors, the slow pressure of money. The unease in this song is less about spectacular decay than about the daily work of getting by and the odd calm people adopt to do it.

That is also why the song resists easy villains. The shaking is not pinned on a single cause. The tone is that of a writer who has watched a pattern repeat for years and keeps describing it anyway.

A record that turns inward

NPR's review treated the album as a major step forward from the band's previous record, Under Color of Official Right, and as a move inward. Rather than hiding behind artistic affectation, the critic wrote, the band uses its sound as a canvas for personal observations, memories and sharp social critique, and the result is anything but polished^[1].

That unpolished quality is part of the appeal. A song about a shaking body or society would feel false if it were smoothed over, and the record's rough texture lets the anxiety stay anxious. Heller found the album simmering, brooding and unsettling, which is a fair summary of the emotional temperature in which this track sits^[1].

Another song on the album is named for Casey's mother, Ellen, and he has said it is the only song about her. He wanted to avoid sentimentality without being clinical, so he wrote about her condition and the passing of time, keeping the focus on the inevitability of time itself^[2]. Placed beside that, the shaking here can be heard as part of a larger meditation on bodies that falter and minds that cannot be fully known.

Other ways to hear it

The most literal reading is personal: a narrator reporting on a body in distress, whether from anxiety, illness or exhaustion, and puzzling over it. The album's concern with the mind and with aging gives that reading real weight, as does Casey's work in a nursing home, where bodies and minds fail in plain sight.

A second reading is political and social, in which the shake is the tremor of an economy or culture straining under its own pretense. This is the reading NPR's review leans toward, and it fits the manufactured-contentment idea^[1].

A third is spiritual. Casey's altar-boy past and his taste for religious and occult oddities suggest an observer raised on belief who now watches it from outside, still sensitive to the tremor that faith, or its absence, can cause. Shaking has long been a sign of awe and dread alike, and the song does not choose between them.

None of these has to win. Casey has said he likes that the central idea of the record has never been pinned down by philosophers^[3], and the song seems to share that preference for open questions over closed ones.

Why it lingers

Plenty of protest music tells listeners what to think. This song does something harder: it makes them sit in a feeling that has no name yet. The unease it describes is common, a vague sense that the surface is too smooth and that something below is moving.

It also rewards return visits because of what came after. Knowing that Anacita grew into a full setting on the next album, you can hear this track as the first sketch of a map. And knowing how the band later moved toward more spacious, searching writing, you can hear how much of that curiosity was already present in this tense, grinding performance.

The question in the title never gets a definitive reply, and that is the honest choice. The shaking continues. The song's achievement is to make that continuing feel less like a failure of explanation and more like an accurate picture of how a great many people actually live.
