About

Rahel Mueller, born in 2001 in the Swiss canton of Aargau, is a versatile musician whose artistic journey began at an early age. She wrote her first songs at five and started playing acoustic guitar at eight, quickly developing a distinctive sense for melody and songwriting. At 11, she joined the youth promotion programme of the Bluesfestival Baden, where she received formal coaching in songwriting and vocals. During this time, she contributed to four full length albums with the programme’s project band and released her first solo EP, The Storm.

Her work gained international recognition early on, culminating in a first place win at New Zealand’s Smokefree Rockquest with the song Running. At 18, she completed her high school diploma with a focus on music and self produced the EP Wires. Under the mentorship of ECHO Award winner Max Frankl, a project band was formed to bring her songs to the stage.

Rahel has since performed well over 100 live shows, including appearances as a support act for The Comets, Bill Haley’s legendary band, and on the main stage of the Badenfahrt Festival. In 2023, she won the BandX Nordwest competition with her band Mollusca, where she is active as songwriter, lead vocalist, and band leader. She is also the lead singer of Helium Moth and works regularly as a bassist and session musician, collaborating with artists such as ok average and FINREY.

Alongside her band projects, Rahel has directed and arranged for the Pop Choir PRISMA in Baden since 2020. In 2025, she joined Seraina Telli on her European headline tour and summer festivals, performing on bass, guitar, keys, and backing vocals, and sharing stages with Swiss rock icons Gotthard and Krokus.

In 2025, she released new music with both of her bands, including the Helium Moth EP TELL US WHAT YOU DID WHEN THE LIGHTS WENT OFF and the Mollusca LP SEDATE ME!.

Known for her strong musical intuition, adaptability, and drive, Rahel Mueller moves confidently between genres and roles. With an optimistic mindset and clear artistic vision, she continues to pursue ambitious goals and expand her creative horizon.
