Rahel von Arx, the creative mind behind Minimalist Worrier, startet her musical career playing the flute in her local orchestra. Expanding her instrument portfolio, she added acoustic guitar and later electric bass to the ever-growing list. Taking part in Helvetiarockt's band workshops in 2018, she established her first acoustic duo Fast Forward, which later transformed into her current band called Mayra.

Delving deeper into the field of electronic music production and music technology, von Arx went on to study those subjects at the London Academy of Music Production. Back in Switzerland, she's working on her solo project called Minimalist Worrier, in which she combines her musical know-how and strives to produce and relase her music single-handedly.
