Bio
The Carbon Dioxide Ensemble (CO2E) performs live original electronic music with interactive visuals. Members include Thomas Lundy, who articulates a large Copper Heart with dry ice, creating acoustic metallic textures; Mark Mosher on Live Synths, Sampling, and Visuals, sculpting the Copper Heart sounds in real time into a cinematic electronic soundscape where the acoustic material becomes evolving rhythmic patterns and melodic arcs; and Victoria Lundy on Theremin and Live Electronics weaving into the composition and providing melodic interludes.
Each show is unique and takes the audience through a journey of movements from sound collage, to Theremin interludes,to beat-driven electronica. Throughout the performance, immersive visuals with live camera input and real-time visual FX transform dynamically, moving in synchronization with the live musical arrangement.

Phantasm October 2025 Review
We were interviewed About Our October 29th Screen Scream Pre-Film Concert at Denver Film Center (and More) on the Queen City Sounds Podcast S2E17 podcast.
Some of Denver’s Most Challenging Music Finds a New Audience at DU…
DU is certainly no stranger to experimental music on campus, but it is certainly rare for this sort of performance to happen at a university in general…
Westword Magazine
Perhaps out of this performance, a new crop of adventurous musicians will take root in Denver or at least a greater awareness of the existence of an experimental scene in Denver spread to people who might be completely ignorant of it.
History
The Carbon Dioxide Ensemble descends from Denver’s Carbon Dioxide Orchestra, a group that performed in the 1990s and early 2000s. An earlier incarnation of the CO2 Orchestra performed in the 1980s.
The Copper Heart was built and played by William Valdez. The Orchestra had a changing membership that at various times included David Dickson, Leroy Jaramillo, Victoria Lundy, Eduardo Mendez, Jason Mieger, and Bruce Nickerson.
