For press enquiries or enquiries regarding the collection of released Voice Gems or the exhibiting of the creation of Voice Gems, please get in contact for more information.

The VOICE GEMS project is a vibrant, unprecedented meditation highlighting the most remarkable, influential, and critically endangered voices on earth to generate digital gemstones and physical sculptures. The works exist as print, 3-D print, digital video, large scale projection and cast sculpture.

The project aims to become the worlds leading curated vocal archive, capturing vocal moments and expressions to generate precious digital objects. 

The colours and structure of the gemstones are generated in real-time from gifted voice data and recordings. A one-of-a-kind voice piece capturing the liminal space between human connection and the vast anonymity of the internet.

Reeps100 (Harry Yeff) and Trung Bao are two of the world's leading vocal experimentalists living today, both utilizing an almost inhuman vocal range. As artists, they have collected hundreds of vocal techniques from around the world, with the aim of pushing the human voice to its unknown limits. 

In 2019 Reeps100 (Harry Yeff) created the first digital sculpture generated from the voices of two lovers. The work was used as a marriage proposal gift, replacing the traditional diamond gemstone and offering a viable alternative to an industry historically associated with environmental depletion and human conflict. 

Yeff’s lifelong collaborations with the world's leading voice artists and academics have shown him that voice is mankind’s most precious tool and one of nature's greatest achievements: it is the purest form of self-expression, predating even language. His multidisciplinary work encompassing AI, VR, and kineticism alongside brilliant technologists, engineers, technicians, and academics to actualize the artistic representation of voice has culminated in the VOICE GEMS series: a visually stunning way to inspire dialogues about value and humanity using new media.

All gems created for the archive are logged and numbered.

"Traditions like the engagement ring are open to innovation. No system is perfect, but if we continue to mine the earth's physical resources, I would like to simply introduce innovative and provocative alternatives using technology."

    LEIPZIG INTERNATIONAL BALLET

    FUSION is a story of balance between the archetypes of human, machine, and nature. Much like a chess grandmaster using any method possible to improve play, composer Harry Yeff (REEPS100) employs every available approach to push his voice beyond what we believe to be possible. Yeff possesses one of the most unique and varied vocal ranges on Earth, and through his collaboration with A.I, he has surpassed even his own limitations.

    SEE SOUND

    'See Sound' is a generative artwork experience that creates sound sculptures based on the human voice. Participants engage with the artwork via a microphone and hardware interface. They can trigger different visual constructions within the music visualizer, based on vocal experimentation. Each construction is a sculpture unique to its creator.

    DOES NOT EXIST VR

    'Does Not Exist' won the award for Best Sound Design Experience at the 2017 Raindance Film Festival.

    In collaboration with media innovation giants The Mill and Aurelia Sounds, I scored and performed in does Does Not Exist, the worlds first Virtual Reality music video made with gyroscopic 3D sound. The two and a half minute video shifts dynamically between acoustic experiences and atmospheres, combining abstract environments with surrealist elements and haunting, vocal composition. I am portrayed as an unearthly figure jumping freely between a playground of worlds, the experience transmits with physical and sonic accuracy an unworldly journey.

    POLYPHONIC PLAYGROUND

    In collaboration with Fashion Space Gallery and Studio PSK, Yeff created Polyphonic Playground—an interactive sound installation blending childhood play with musical innovation. Swings, slides, and climbing frames were reimagined with electric paint and trigger pads, transforming the structure into a large-scale instrument. By removing traditional tools, Yeff challenges musicians to explore sound through movement, curiosity, and play.

    VOCAL VIBRATION IN WATER

    A desire to visualise vocal music inspired me to experiment with audio-visual work and physical phenomena as early as 2012. Cymatics — the use of vibration as a medium to move, organise and control matter — has since constituted a prominent focus in my work.

    I continue to reinterpret cymatics as a means for invention, developing custom-designed, large-scale visualisers for performance. The Cymatics photography series and live Cymatics performances received an ARS PRIX nomination in 2016.

    Attention. Deficit. Order.

    Attention. Defecit. Order. was my first major solo exhibition in London. With the exhibition, I explored the often-overlooked benefits of mental processes associated with Attention Deficit Disorder, including high functionality and hyperfocus. I wanted to challenge negative notions of hyperactivity and celebrate complexity through multi-media sensory installations demonstrating high levels of complexity, precision and cognitive flow. I wanted to subvert the idea of chaos normally associated with ADD.

    YEFF & HOPPER

    As part of the exhibition Attention. Deficit. Order., artists Yeff and Ben Hopper presented The Circle of Naked—a participatory body painting performance exploring empowerment through vulnerability and self-expression. Over fifty participants, including women, men, and children, became living canvases, engaging in a collective act of transformation. The physicality of the paint sparked a range of emotional responses, from shyness to bold embodiment, blurring the lines between observer and performer.
