con:trust – the German Accordion Duo between Classical, Contemporary, and Musical Boundary Crossings

A duo full of passion, virtuosity, and surprising radiance

con:trust is a German accordion duo consisting of Marius Staible and Daniel Roth, known for their unusually open and stylistically diverse musical career. The ensemble navigates between classical literature, contemporary music, original compositions, arrangements, and performative formats that bring the accordion out of its niche. It is precisely this blend of technical precision, joy in performance, and conceptual awareness that makes con:trust one of the most exciting young chamber music projects in the German-speaking world.

The name represents contrast and trust, two poles that shape the duo not only musically but also as an artistic stance. On stage, this creates an intense presence where subtle dynamics, rhythmic energy, and a remarkable sense of tone colors come together. con:trust sees itself not merely as a repertoire ensemble, but as a creative laboratory for the accordion as a contemporary instrument.

The early years: Friendship, study, and a shared sound

The story of con:trust begins in 2016 at the accordion master class in Ottweiler, where Daniel Roth and Marius Staible, already familiar from previous courses and competitions, were placed in the same room for the first time. This encounter led to a close collaboration, which, according to the duo, soon developed into an almost daily musical practice. In 2017, the newly named duo made its first appearance at a renowned chamber music competition in Val Tidone, Italy, where they won first prizes in two categories as the youngest participant duo.

This early success marked more than just a competition victory. It demonstrated that two young musicians had found each other, whose artistic development was based on mutual trust and a clear delineation of their artistic identity. Early on, con:trust connected the idea of treating the accordion not as a folklore instrument, but as a versatile medium for chamber music, transcription, and contemporary composition.

Building a distinctive musical career

Following their initial competition successes, the duo performed at the Berlin Philharmonie and gave concerts at various festivals and event series, including the Kurt Weill Fest, the Liquid Sound Festival, and the Bach Festival. During this time, the duo developed a repertoire that included classical works by Bach, Scarlatti, and Ravel, as well as jazz transcriptions and music from the 20th and 21st centuries. This programmatic openness provided con:trust with a profile that clearly distinguishes it from traditional accordion acts.

A particularly important phase for their artistic development was their time in Weimar. There, Daniel Roth studied music theory as a secondary subject, while Marius Staible focused on new music. From these differing emphases arose a productive tension that the duo purposefully translated into composition, arrangement, and production of new music. Thus, con:trust developed not only a repertoire but also its own sound cosmos.

Between original music, arrangements, and experimental production

A central feature of con:trust is the work on new music for two accordions. In 2019, two original compositions for this configuration, “Rayo de Sol” and “El Mafioso,” were released, documented on the duo’s website. At the same time, con:trust published live and studio material that highlights the stylistic breadth of the project: from baroque and romantic arrangements to more modern, jazz-influenced, and experimental approaches.

Notably, their collaboration with cellist Eloy Medina resulted in an EP where innovative soundscapes from accordion and cello were woven into melodic house and drum ‘n’ bass beats. With this, con:trust consciously stepped away from a purely acoustic chamber music perspective and opened itself to a hybrid production that connects classical, electronic thinking, and improvisational impulses. This artistic movement points to a rare consistency: to not only interpret the instrument but to conceptualize it anew in terms of sound.

Awards and recognition in the professional world

The list of awards underscores the duo's authority in the accordion and chamber music fields. Marius Staible won first prize at the International Accordion Competition in Vilnius in 2021, while Daniel Roth claimed first prize in the variety category at accordeons-nous.org in Belgium in 2023. In 2022, con:trust was awarded the Franz Liszt Prize at the Hochschule für Musik FRANZ LISZT Weimar as a chamber music ensemble.

These honors are more than mere career milestones. They attest to the high level of professional quality that the duo possesses and its acceptance in a milieu that requires both classical excellence and programmatic curiosity. Particularly, the Franz Liszt award carries symbolic weight, as it honors the accordion tradition of a college that had never before recognized such an ensemble in this way.

Social media, audience, and artistic visibility

During the pandemic, con:trust's public presence changed significantly. The duo built a broad reach on Instagram and TikTok and became known to a larger audience through entertaining videos, particularly among younger musicians. The duo's website notes that this work was featured by MDR Thüringen and Deutschlandfunk Kultur, and con:trust was perceived as a role model during this time.

Facebook also played a role as a documentation space for vlogs and behind-the-scenes insights. This digital presence is remarkable for a chamber music duo, as it complements the classical concert format with a low-threshold, contemporary approach. con:trust utilizes media not merely as a marketing tool but as an expansion of the artistic space.

Concerts, projects, and the opening of the accordion

In 2022, the duo collaborated with Live Music Now in Weimar on a project involving inmates from the Hohenleuben correctional facility and performed a concert in Greiz composed of texts from the prisoners and compositions by the duo. This work was subsequently featured by ARD and ZDF, demonstrating that con:trust takes the societal context of music seriously. In this context, the accordion becomes a medium for exchange, empathy, and cultural participation.

In 2024, con:trust took another spectacular step by performing on “Das Supertalent.” The performance, without playback, drums, and large show elements, relied on the pure presence of two musicians and their instrument. At the same time, ten new compositions for the accordion duo were premiered in Toronto, New York, and Berlin; this project is considered one of the ensemble's most important because it expands the already rare original literature for this configuration.

Current projects: Weimar, theater, and new horizons

In 2025, con:trust remained present and versatile. The duo participated in the Weimar and Bayreuth performances of “Jedermann” and shared the stage with several actors. Moreover, con:trust was selected for the John Cage Award 2025, where they presented a program featuring premieres, improvisations with ChatGPT, and works by Pauline Oliveros, Uroš Rojko, Chen Shuhe Yue, José Eduardo Muñoz, and Jukka Tiensuu.

These current projects illustrate the core of their artistic identity: con:trust does not merely stop at virtuosic reproduction, but works on an open, dialogical, and contemporary form of accordion art. The duo envisions chamber music as a living system where interpretation, experimentation, physicality, and the present intertwine.

Musical style and cultural influence

Stylistically, con:trust thrives on contrasts. The duo blends classical lines with rhythmic precision, sonic transparency, and a strong sense of dramatic emphasis. In their interplay, technical mastery and rhythmic flexibility are evident, as is the ability to shape arrangements and original compositions into a cohesive artistic language.

The cultural influence of the duo primarily lies in the reevaluation of the accordion. con:trust demonstrates that the instrument goes far beyond traditional attributions and holds remarkable relevance in chamber music, new music, crossover formats, and social projects. This versatility makes the duo equally exciting for music lovers, festival audiences, and young instrumentalists.

Discography and documented releases

The documented work of the duo includes the original compositions “Rayo de Sol” and “El Mafioso” for two accordions from 2019, as well as a CD featuring recordings of lost compositions from the Loheland movement, created in collaboration with the Vonderau Museum Fulda and the Loheland Foundation. Additional releases include the EP with Eloy Medina and the solo works “A Daily Practice for Failed Oracles” and “Jeux de lumière” published on their secondary channel. These releases are characterized by their connection of repertoire preservation, new creation, and experimental sound research.

The discography of con:trust is less oriented towards chart-topping hits than towards musical relevance and conceptual depth. This is precisely where their strength lies: The releases document a development that leads from classical competitive success to an independent artistic signature. Those who listen to the duo encounter not mere virtuosity, but a reflective, contemporary aesthetic.

Conclusion: Why con:trust is a duo worth experiencing

The duo represents a musical career that has grown from competitive successes, creative projects, social engagement, and experimental curiosity.
