40.4 Logo

by Sean Winters

An audio-forward intermedia sonic summit, the fourth annual 40.4 Festival will feature a lineup of events focused around the state-of-the-art 44 channel spatial audio array in B2鈥檚 Black Box Experimental Studio. Previous years have featured Natasha Barrett, Tarik Barri, Monica Bolles, Eric Raynaud, Timothy Cleary, Mariam Gviniashvili, Ernst van der Loo, Nicola Giannini, R.A. Jones, Krzysztof Gawlas, Jeff Merkel, Brian Kane, David Fodel, Jakob Gille, Enrique Mendoza, David Zicarelli, and many others!

About Sean Winters


Sean Winters, B2 Scholar in Residence, is equally interested in creating content for high density loudspeaker arrays, head-mounted displays & AR tech, and live intermedia performances. Sean's creative practice and research center around exploring both the creative and therapeutic applications of spatial audio in XR contexts, specifically within the live events and healthcare/wellness sectors.

Join Sean Winters听to listen deeply to B2's 44 channel high density loudspeaker array. Possibly reminiscent of John Cage鈥檚 Imaginary Landscapes and embodying Rodrigo Rios Zunino鈥檚 concept that Radio is a Virus from Outer Space, radio44 is a spatial sound event that's {quasi?} live-performance, and partially curated by the universe.

L'Astra Cosmo and Sharifa Moore utilize the advanced intermedia technologies at B2's Black Box Experimental Studio including the high-density loudspeaker array and large format projection.

Grief takes different forms and sometimes can be as simple as a misplaced memory or the unsettling that occurs with change.听Awash Away is a video processing short accompanied by a live sound performance that engages in productive disorientation through an unfinished self.听

Sharifa Lafon (she/her) is a curator and artist working in time-based experimental media. She creates and presents moving-image projects, installations, and public programs that explore perception, embodiment, and interconnection, often through collaborative, community-rooted production. Her work spans exhibitions, screenings, and large-scale projection projects.

Colorado-based music artists L'Astra Cosmo present their new audiovisual live show, "Lightphorms" 鈥 an electrified exploration into the secret world of phosphorescent visual forms generated using sound and voltage-controlled analog signals captured from vintage oscillographic CRT displays and modified vector game displays from the early 1980's.

Incorporating vector and video synthesis, audiences experience early analog computer animation techniques in a new context: hyper-chromatic visual form. "Lightphorms" explores the direct relationship between sound and light combined with artificial depth perception, created by exploiting a visual illusion known as chromostereopsis that can be enhanced and observed through ChromaDepth鈩 3D glasses, taking audiences to new heights of synesthesia.

Important note: Portions of the performance will exhibit moments of stroboscopic light, therefore audience members who are sensitive to flashing light should take this into consideration.

For 20 years, Jahnavi Stenflo and Nathan Jantz have been working together creatively in different capacities, from curating to performing live. First appearing at 2016鈥檚 clandestine annual outdoor event, Lunar Lodge, their live performance of 鈥淔requencies Unseen鈥 was staged at the Lafayette Electronic Arts Festival later that year. While continuing to evolve their AV live performances, they were invited in 2023 to participate in a residency at Signal Culture, resulting in a piece currently in the group exhibit, 鈥淭he Experimental Frontier鈥 at the Loveland Museum, in Colorado.

L鈥橝stra Cosmo鈥檚 work is rooted in a future-retro aesthetic: Seeking a hybrid visual language that lives unexplored between the past and the future, science and mysticism, technology and organic matter. Utilizing oscilloscopic displays, they approach 鈥渙bsolete鈥 video technologies not as relics, but as re-activated mediums and interlocutors. Treating these elements as catalysts in an explorative dialogue, their work directly addresses perception, entropy, and the aesthetics of signal decay. This methodology allows for critical reclaiming and renewal, moving the axis of experimental video forward by reaffirming its utility as a current process for discovery and examination in signal aesthetics through committed technical practice.
