4/23 12PM EDT – 4/24 12AM EDT

2020 has been a year of isolation for everyone. Performing artists have been especially affected by the pandemic restrictions. However, this time spent physically apart from our families, friends, collaborators, and audiences has also highlighted something for artists: the value and convenience of meeting, collaborating, and performing with other people around the world via the Internet (and our planet is happy, too, about less carbon emissions!). At the SEAMUS 2021 Virtual National Conference, CCRMA is delighted to host a 12-hour telematic audiovisual event. The selected musicians and visual artists will present both individual and collaborative live acts throughout the day. Between 6:30–8:30pm EDT, we will open the virtual playground for even more partnerships between participating performers, including free improvisation.

We invite you to leave comments, ask questions, and interact with the artists and other audience members through the chat window.

The Core

The Core is a group of six musicians that formed when the lockdowns due to the coronavirus pandemic first started in March 2020. Since then, they have been live streaming weekly telematic concerts of electroacoustic improvisation. Their ongoing series, the Quarantine Sessions, has reached number forty-eight and they have also performed at two virtual conferences. In their one-hour weekly sessions they have had over thirty guest musicians and visual artists from various countries, including the US, Canada, Ireland, Germany, Lithuania, Australia, and the UK. The members of the group are: Constantin Basica - keyboards and live electronics (Stanford, CA) / Chris Chafe - Celletto, dilruba, and Stegasaurus (Woodside, CA) / Henrik von Coler – hypermodular synthesizer (Berlin, DE) / Fernando Lopez-Lezcano - synthesizers and live electronics (San Carlos, CA) / Juan Parra - guitars (Ghent, BE) / Klaus Scheuermann - modular synthesizer (Berlin, DE).

Dilate Ensemble

Dilate Ensemble are Carole Kim (S. California), Gloria Damijan (Vienna), Jon Raskin (N. California), Luisa Muhr (NY/Vienna), and Scott L. Miller (Minnesota). This audio-visual band explores virtual spaces. Seeking to find ways to still connect with other performers during a pandemic, the members of Dilate Ensemble met while participating in the NowNet Arts Lab Ensemble led by Sarah Weaver. As a satellite to this ensemble we dove into an exploration of how we might be able to engage in audio/visual improvisation online. Kim has compressed her work in video installation to fit beneath her kitchen table. This intimate live "venue" provides an illusionistic physical space that readily accommodates a convergence of online live presence. The ensemble collaboratively develops their work, which involves a shared visual element delivered over Zoom. They use Netty-McNetface to mix the audio in Scott's studio, where he individually processed the various audio tracks in Kyma, which is then monitored by the ensemble in Netty. Scott uses Netty/Zoom/OBS to produce a live a-v work that is streamed to YouTube/Facebook/Zoom as preferred by the venue. By embracing the latent nature of telematic performance, the ensemble has developed an artistic practice that is idiomatic to the venue of networked audio-visual art. This activity is supported in part by the Austrian Cultural Forum, New York City (ACFNYC).

Steven Kemper

As a designer of robotic musical instruments, Steven Kemper is interested in the ability of machines to facilitate new avenues for sonic exploration, both by taking advantage of the unique timbral possibilities afforded by mechatronic actuation, as well as exploring the ways that musical robots’ capabilities differ from human performers. His recent work explores the collaborative relationship between human performance and robotic sound production, using sensors to translate the movements of a human performer into sound produced by musical robots. Not only does this approach produce novel timbral results, but also evokes the cyborg: a hybrid body that blurs the lines between human and machine.

duo B. vs. viDEO sAVant

duo B. vs. viDEO sAVant is an intermedia trio featuring live processed video by veteran media artist Charles Woodman (viDEO sAVant) and live acoustic music by the improvising percussion and acoustic bass duo of duo B. (Jason Levis and Lisa Mezzacappa). Based in the San Francisco Bay Area, duo B. vs. video sAVant creates revelatory moments where the distinction between music and video, sound and image melt away and a new whole emerges from the flow between individuals and media. The group’s immersive performances explore layered audiovisual soundscapes, from frenetic juxtapositions to meditative fantasies. Moods shift from contemplative to chaotic, with slowly evolving visual and sonic narratives collapsing into psychedelic colorplay fueled by dynamic and electrifying ensemble interaction. The result is a live soundtrack to a film created in the moment—in front of a live audience, in response to a specific time, place and physical space.

Cecilia Suhr

Crossing the boundaries between audience and performer, vision and sound, motion and stasis, digital and analog, seen and unseen reality, Cecilia Suhr’s improvisational performance on the violin, voice, and cello often interacts with live electronics and video or fixed media. She often invite audiences’ participation as a part of live performance to heighten audiences’ intimate and embodied experience while honoring unity and collective bonding. So far, her intermedia performance works incorporate interactive techniques such as face-tracking, color tracking and drawing with sound to create a unique audio-visual experience. She also carefully design a human focused interaction along with the art installation/camera installation. Overall, her creative practice yields a unique combination of various mediums such as performance art, movement, video, installation while an experimental comprovisation/improvisation in an electro-acoustic style of music is the central element that anchors all mediums.

Fernando Lopez-Lezcano

Fernando Lopez-Lezcano enjoys imagining and building things, fixing them when they don't work, and improving them even if they seem to work just fine. The scope of the word "things" is very wide, and includes computer hardware and software, controllers, music composition, performance and sound. His music blurs the line between technology and art, and is as much about form and sound processing, synthesis and spatialization, as about algorithms and custom software he writes for each piece. He has been working in multichannel sound and diffusion techniques for a long time, and can hack Linux for a living. At CCRMA, Stanford University since 1993, he combines his backgrounds in music (piano and composition), electronic engineering and programming with his love of teaching and music composition and performance. He discovered the intimate workings of sound while building his own analog synthesizers a very very long time ago, and even after more than 30 years, "El Dinosaurio" is still being used in live performances."

Daniel McKemie

Daniel McKemie has an extensive background in live performance and improvisation as both a percussionist and on electronic instruments. He has spent many years coding his own software, building hardware, and joining the two when applicable. His practice of improvisation really hit a stride in my graduate studies at Mills College and after, where he spends his time in the Bay Area circuit playing his own sets, but also alongside many other great performers. This past year I has done a number of performances online and have spent a great deal of the last few years utilizing web technologies to further distance collaborations, many of which are rooted in improvisation.

Interact with the performer during the live set here.

Brad Decker

As a double bassist and improvisor, Brad Decker has been exploring the intersection of extended techniques, computer processing, and improvisation for over 15 years. In his practice, he explores the immediacy of expression through hands-on exploration of acoustic elements of the double bass and how they can be processed digitally to create an immersive, overarching sonic environment. Each project captures the essence of the moment, time and place, emotion, and life experience. These have been recorded in different capacities, and have led to a series of scored solo works for double bass and computer. He continues to perform as a double-bassist using structured improvisation and live computer processing in numerous capacities, namely solo works, group ensemble collaboration, video-art installations, and film soundtracks. Notable performances have been in Mexico, Australia, Italy, France, Brazil, and Canada, as well as at numerous venues in the United States.

Seth Shafer + Brad Robin / Sarah Church

Seth Shafer’s artistic practice represents musical exploration at the extreme edge of performance. He develops interactive installations and improvisational performance environments that are audience-involved meta-instruments. His work includes generative pseudo-hologram installations, interactive floor projection systems, and live data sonification exploiting privacy loopholes and feedback networks. He also looks for opportunities to explore ephemerality and multiplicity in live performance. This often involves performance situations that have limited or impossible rehearsal scenarios, purposeful impediments to ensemble coordination, live sight-reading, and unavoidable failure.

Brad Robin composes and conducts music in a multitude of styles for soloists and ensembles ranging from jazz band to contemporary chamber groups and orchestras. Compositions have also included a computer component designed to manipulate and augment the sound of acoustic instruments. As a pianist and keyboardist, he composes and performs music for dance, theatre, film and multimedia performance art. In addition to the United States, his music has been performed in Croatia, Mexico and New Zealand.Recent performances include Phase: Transmuted Agony for chamber ensemble, fixed media and dance, International New Directions in the Humanities Conference in Chicago, Texas Dance Improvisation Festival, and the Uzmah–Upbeat festival in Croatia. Having completed a PhD in Music Composition from the University of North Texas and Master's degree in music composition at DePaul University, he currently resides in Chicago with his wife Nicole and continues his studies at Northwestern University.
