Victoria Lundy has long been a figure in the avant-garde underground in Denver. She’s been a member of Carbon Dioxide Orchestra and currently plays with the Inactivists and the Jackson Induced Mutant Laboratory, and she and her mathematician husband, Tom, have also been heavily involved in the periodic Concrete Mixer event, which showcases performances of musique concrète. A true composer and an excellent crafter of songs and soundscapes, Lundy has occasionally performed solo with a theremin and synthesizer in recent years. Her new album, Miss American Vampire, is a collection of songs played on the theremin; she’ll celebrate its release with a show at the Walnut Room on Friday, October 30, which will also include the visuals and music of synth wizard Mark Mosher and like-minded electronic artists Keldari Station and Church Fire. Lundy will demonstrate that the theremin can be more than a science-fiction-movie special effect or a quirky musical affectation.
