Amma Ateria is an electroacoustic composer/sound artist born in Hong Kong, but currently working in San Francisco and New York. She studied with Maggi Payne and Fred Frith, and has performed with many illustrious artists like Pauline Oliveros, Ikue Mori, Erik Friedlander, Matmos, John Zorn – to name but a few.

Concussssion I is ‘an auditory meditation on cognitive recovery’. The compositions, ‘developed during concussion recovery (since June 2021) utilizes brainwave entrainment, time shifts, and changes of neurological responses to DELTA, THETA, ALPHA, BETA, GAMMA waves as materials and focal point. The selected pieces are reflections of my experiences with stillness, unconsciousness, and auditory hallucinations, which became starting points towards levitation, transformation, and neurogenesis.’ 
The four SSSS in the title, by the way, ‘symbolize a period of auditory disorientation I encountered, such as instances of prolonged frequency extension of sibilance in human speech’.

Electroacoustic music can sometimes be highly abstract and detached from human emotions. But here, the combination of this intense personal event with Ateria’s experience as a composer and a sound artist results in an electroacoustic album that feels deeply human. Exploring psychoacoustics in binaural beats, she is capable of ‘transforming deafening noise into meditative stance’.

With Concussssion I, you can share her experience without the downside of having a concussion yourself.
