"I am a bassist, improviser and interpreter and play music in the area between jazz, improvisation, new music and pop.

I work internationally as a solo artist, with the band Ensemble 5 and as a sideman; an extensive discography on labels such as Leo Records, Hat Hut, Unit Records and TCB documents this work.

My music is inspired by everyday life and I look for illiteral or musical answers to the questions: What are we and what depths of passion, feeling, perception and thought can we reach?

My goal is to play clearly, concretely and directly. Without intention and in unconditional sincerity towards reality, in order to get closer to the point at which what is hidden behind concepts, ideologies, styles or common listening expectations becomes audible.

In order to develop a personal and new music/musical language, I research the musical tradition, current musical trends, groove/time, sound and the way the bass is played in relation to this.

At the age of eight I started playing the cello and discovered chamber music, and at the age of 15 I switched to the double bass and jazz. From 2003 to 2008 I studied at the Basel University of Music, Jazz Department, and since 2008 I have been working as a freelance bassist, stylistically independent."
