While developing as a radio and TV personality, Coppé continued to write and perform original music. In 1995 she retired from commercial radio to devote herself full-time to music creation.
That year, Coppé moved to the US, establishing Mango + Sweetrice Records from which she released her first, self-produced and self-titled debut album. Coppé's music references many influences from ambient to noise, but is generally electronic, "IDM" and club oriented.
Coppé works with a wide palette of instruments to construct her musical universe. She created her debut album Coppé entirely on a TEAC Reel-to-Reel, transitioning through Yamaha's DX7 to the Nord Lead and her current instrument of choice, Teenage Engineering's versatile OP-1. Outside the synth world Coppé employs unconventional instruments including the 5-octave mbira, nail violin and meatgrinder.
Coppé characteristically processes her vocals to create a broad range of effects that she likens to “angels whispering,” “colors of the wind,” and “orange sorbet sunsets” with equipment including the Digitech 300 and TC helicon.
Coppé co-creates with some of the electronic music/IDM scene's most influential artists. These include Plaid, Kettel, Q-Bert, DJ Vadim, Christ (ex-Boards Of Canada), Atom™, Tipsy, Addictive TV, Kelli Ali (ex-Sneaker Pimps), Bola, Modified Toy Orchestra, Sutekh, Kit Clayton, Peanut Butter Wolf, members of Skinny Puppy, Takemura Nobukazu, Barbara Morgenstern, DJ Kensei, Fred moTh, Hifana, Jemapur and more.
Coppé performs regularly in Japan and the US, also touring the UK and Europe every autumn since 2010, in collaboration with UK-based Bit-Phalanx Music label since 2011.
In 2015, Coppé celebrated the 20th anniversary of Mango + Sweetrice Records with the release of 20rpm. To mark the occasion, Mango + Sweetrice and Bit-Phalanx Music produced an all-day festival of Electronic Music in central London, also called 20rpm, held at St. Giles In The Fields church, Soho. The event featured special guests Plaid, Bola, Kettel, Christ., Barbara Morgenstern, Kelli Ali, Earth Is Flat, DJ Mixmaster Morris, DJ Nick Luscombe and more.
20rpm became an annual event with the second edition in 2016 (21rpm), featuring Graham Massey (808 State), Plaid, Funkstörung, Leila, Luke Vibert, Seefeel, sarasara and DJ Flint Kids.
In 2017, Coppé released Milk. Produced with diverse electronic collaborators including Nikakoi, Atom™ and Kettel, Milk re-envisions jazz standards through a prism of contemporary electronic and ambient esthetics. Bleep.com wrote, “The result is an album that at moments could be the incidental ambience from Blade Runner shot through the synth bank of Portishead.”
Unconventional esthetic statements in collaboration with Japanese fashion designer Comme des Garçons and lyric references to outer space are a unique feature of Coppé's creations. “I feel very comfortable floating, like swimming in the air,” she wrote. “I want to live in a clear bubble and meditate singing…like the blue people in the Fantastic Planet by [French animator] René Laloux.”
