Pressure is the medium of wind players. Wind instruments all sound thanks to pressure differentials, whether that’s the rush of wind over a lip plate or a steady, buzzing exhalation through pursed lips. Ka Baird and Chris Ryan Williams (HxH) are wind players well- schooled in the power of using pressure and movement to amplify the mystery of an invisible force animating a metal tube. They augment their instruments, flute and trumpet respectively, with electronics, sometimes obscuring the acoustic sound source, sometimes making it hyperreal. Flutters of lip and tongue slither over the listener’s ear, and sustained tones become a dense fog, pushing on other kinds of visceral, emotional pressure points.
On Enthalpy, Baird and Williams’ first album as a duo, the energy they conjure feels barely contained, the pressure built up to a breaking point before spilling out in multiple directions at various speeds. They borrow the title from thermodynamics, referring to the total energy of a system based on its pressure and volume. The music flies out in bursts; it seeps and oozes, flows with intention. It is an incredibly rhythmic work without any hint of meter, full of sounds that punctuate with the thud of a dart hitting a bullseye. Williams’ capability to conjure swirling atmospherics, as well as his remarkable ability to pull fragments of melody from the haze, fit puzzle-like into Baird’s exclamations and the eruption of electronics that often dovetail them. The duo draws on tones from nearly the entire range of human hearing, from nimble but bulbous throbs of sub-bass to pinprick flickers of ultra-high end.
The sessions that produced Enthalpy were completely improvised, showcasing a degree of mind-meld that belies each participant’s thrill at approaching the unknown. This isn’t a casual conversation, but an omnidirectional tangle that ties and reties itself into new knots as the album progresses. Williams and Baird have both become ubiquitous presences throughout the New York City experimental music communities, collaborating with innumerable others and learning how their unique approaches work in tandem with similarly expansive thinkers and players. Even in the album’s most spacious moments, there’s a tension between the feeling of being unmoored and yet completely locked in, like the abyss is just one more river to cross. They ford it together before moving on to the next idea in lock step.
For the listener, Enthalpy is often felt in the body as much as it reverberates within the ears. We’re tossed from side to side, made to shoulder the impact of detonating electronics, absorbing these sounds with the feet, gut, and crown. Baird reaches into the back of their throat for guttural growls, and we can almost feel the scratch. As we tread the border of the synthesthetic, it's a reminder of the physical nature of sound, that the space between our ears and the speakers is its own enthalpic system of energy conduction. Move with it, let it move you, and see how it feels.
