The poet Susan Howe is seventy-seven today. A few years ago, she and the musician David Grubbs collaborated on “Frolic Architecture,” a series of multidisciplinary performances that sprang from a book of her collage poems by the same name. Harvard has posted a video of the performance, which is quietly, insistently disruptive. As it progresses, prerecorded shards of Howe’s voice seem to fall into her live voice, and Grubbs fills the space with incidental sounds: insect chirps, gravel and snow and leaves variously underfoot. The performance seems at once to take on weight and ascend into the ether.

Howe remarked on the collage, and the process of recording it, in her 2012 Art of Poetry interview:

HOWE

I am an Americanist. There’s something that we do, a Romantic, utopian ideal of poetry as revelation at the same instant it’s a fall into fracture and trespass. Frolic Architecturecuts itself to bits. It could be that because I am a woman, bullets are more like blanks. What fuels the poems in that collection is the sense of epic breaking into shards.

INTERVIEWER

I’ve heard the recording of your performance of Frolic, and you actually speak—sound out—its fragments and phonemes, those shards. You treat your work as a score.

HOWE

Collaborating with the musician-composer David Grubbs has brought vividly home to me how acoustic a seemingly collaged and visual work can be. Several years ago our first collaboration was for a performance at the Fondation Cartier in Paris, and was based around an early poem of mine called “Thorow.” We collaborated again to produce Souls of the Labadie Tract. The work I have done with David has influenced the course of my later poetry by showing me a range of contemporary music with which I was unfamiliar. It also restored my earlier interest in Charles Ives. I love the way Ives’s musical use of quotation throws connectives to the winds. His work is Romantic and iconoclastic at once.

And in the journal Lana Turner, Ben Lerner wrote with typical acuity about the performance:

I assumed Grubbs had digitally manipulated Howe’s voice in order to mimic the fragmentation of the collages. And Grubbs did often and artfully alter her voice, but it turns out that many of the sounds I thought were digital slivers weren’t. It simply did not occur to me that Howe would be capable of reading such diverse phonemes and even smaller linguistic particles in real time with such precision. But she is: I have never heard a person pronounce “nt” or “rl,” for instance, so exactly. Howe can render even the most distressed text acoustic … Howe’s recorded voice—sometimes digitally cut up, sometimes left alone—alternated or overlapped with the live performance, and Grubbs had made sure that there was little or no perceptible sonic difference between what was digital and what was happening before us; when I shut my eyes, I couldn’t tell. This blurring of the boundary between the live and the recorded was a deft way to indicate how Howe’s poems are at once originals and remnants.
