Kenneth Lee "Ken" Butler (born August 3, 1948) is an artist and musician, as well as an experimental musical instrument builder. His Hybrid musical instruments and other artworks explore the interaction and transformation of common and uncommon objects, altered images, sounds and silence. The idea of bricolage, essentially using whatever is "at hand", is at the center of his art, encompassing a wide range of practice that combines live music, instrument design, performance art, theater, sculpture, installation, photography, film/video, graphic design, drawing, and collage. He is internationally recognized as an innovator of experimental musical instruments created from diverse materials including tools, sports equipment, and household objects. His works have been exhibited and performed in galleries, clubs, museums, festivals, and theatres throughout the USA, Canada, and Europe including The Stedelijk Museum in Amsterdam and Lincoln Center and The Metropolitan Museum of Art in New York City as well as in South America and Japan.
