Born and raised in Charm City, Hedonia’s exposure to the keyboard began with piano lessons in the fourth grade. “I remember trying to change the sound of my digital upright piano as a kid,” she later recalled to the site Atmospheres and Experiments. “I would pitch up the sound to bend the notes or try to alter the sound in some way. What I didn’t know, though, was that I was playing the wrong instrument for that application; what I really needed was a synth.” Thereby having, in her words, “broken the seal,” Hedonia soon made a beeline for a used microKORG at a local music shop. As her zest to make music grew, sequencing came next, via Native Instruments’ Maschine software. Hedonia’s stable of hardware swelled, too, with the Moog Sub Phatty and Prophet ‘08. “Then, when we moved into our house,” she says of herself and M’Olive, “we just kept growing and growing and growing with stuff that we had.” Which led to a breakthrough, when Hedonia began experimenting with modular synthesis — glomming onto it far more than guitar enthusiast M’Olive. “You take off the outer layer, and you get to rebuild the skeleton of the sound. And it’s up to you. There are no presets. There are no built-in sequences. You have to make it all,” Hedonia explained to JazzTimes. “That’s when I started to get interested in actually making music.” A natural tinkerer, Hedonia began making patches, and creating sounds and sequences; the Plonk module, from Intellijel, was a particular gamechanger. As her Eurorack setup continued to expand — “It looked like a spaceship!” — Hedonia quips — she developed what she characterizes as “a hard, weird, industrial sound.” During her so-called “Eurorack era,” Hedonia performed in New York City and Washington, DC, including those put on by the Luminous Abstract collective.. She stayed busy during the lockdown, performing on Flying Lotus’ show, “The Hit.” In 2021, Hedonia not only released her debut album, The Inevitable Collapse, but collaborated with electronic audiovisual artist and composer and Luminous Abstract co-founder Grant Bouvier on the ambient synthwave album Kenopsia. 2022’s Marie Ann Hedonia Presents Marie Ann Hedonia represented a leap forward in songwriting and production quality; she followed it up with 2023’s Temporal Dysmorphia. In 2023, she opted to pivot to more of a classic sound via the Buchla 200-E system — which she would utilize to great success on Pelt’s Woven. She recorded her 2025 EP Quiet Time with that musical tool, as well as a Moog Model 10 and the Polyend Tracker. In 2025, Hedonia branched into jazz via her collaboration with trumpeter and composer Jeremy Pelt, on his album Woven. The Guardian called the eclectic album “a classy outing,” noting the band’s “evident comfort,” and praising Hedonia’s “shadowy presence”; according to JazzTimes, she left “one of the deepest impressions” on Woven. Hedonia’ will release her latest offering, Eclipse, later in 2025 via Paul and Marie’s Country Kitchen. Her most fleshed-out and rangey work to date, the album features collaborations with vocalists Delia Liederschuh, Casey Desmond (featured on the first season of The Voice),, and Black Kite’s Vicki Lynn Tippit.
