“The Art of Sound,” the documentary series co-produced by L-Acoustics and Black Meteor, returns with its second episode — arriving in two parts and built on the series’ premise: that sound is not decoration, but a fundamental
force shaping human biology, emotion, and culture.
Part I, featuring Houston trio Khruangbin, explores the physiological response to sound through live heart-rate monitoring research. Part II shifts to Brazilian DJ, producer, and philanthropist Alok, examining how sound functions as a vehicle for collective experience and cultural identity at scale. Together, the two installments trace sound’s reach from a single body to an entire crowd, starting with what happens, physiologically, when Khruangbin steps into a room.
The series launched in 2025 with Episode 1, “Sound is Fundamental,” featuring musician and multidisciplinary artist David Byrne alongside researchers Robyn Landau and Dr. Erica Warp, and EEG research conducted at L-Acoustics London. Episode 2 continues that methodology, pairing globally influential artists with scientific inquiry, while expanding the scope of both the artistry and the research.
The Khruangbin episode centers on a field experiment tracking listeners’ heart-rate responses during live performance, exploring how music produces measurable physiological change in an audience. The research is being developed in collaboration with CoStars Live Lab at York University, with a conference paper currently being drafted on the findings. The episode asks what happens, biologically and emotionally, when that sound reaches a room full of people.
Where the Khruangbin episode works at the intimate scale of physiological response, the Alok episode (Part II) examines sound’s capacity to create shared identity across vast, diverse audiences. Featuring Greenwich University’s Dr. Martha Newson, the series frames this as sound’s role as invisible architecture, structuring how communities form and how they experience the world together.
“Music is one of the few forces that can unite people without requiring them to speak the same language or share the same background. I’ve always believed that sound can create a sense of belonging and collective identity,” said Alok.
Amber Mundinger, Global Director of Creative Engagement at L-Acoustics, says, “What we kept finding, episode after episode, is that the conversation between artists and researchers produces something neither could reach alone. Episode 2 takes that further. With Khruangbin we see how sound from across cultures lands in a single body, and with Alok we see how one artist’s sound binds a crowd into shared experience. Both are asking what sound is doing to us — they’re just measuring it on different scales.”
Directed by Andrew Lancaster, The Art of Sound is produced by L-Acoustics and co-produced by Black Meteor, with creative direction and storytelling developed in close collaboration with L-Acoustics’ Creative Engagement and Communications teams.
