Marius Staible, born 31st of October 1997 in Halle (Saale) began to play the accordion when he was 4 years old, with an experienced and outstanding pedagogue: Stephan Bahr. 
Very soon he started earning prizes continuously by participating every year in several competitions for young accordionists in Germany such as „Jugend Musiziert” and the „German Accordion Prize”. 
His first piece „Unplugged³" written as an accordion solo in 2013 was awarded with the „Carl Müllerhartung Prize for Composition” and "WESPE 2016", which proves his universal musical comprehension. 
Thrilled by the impressive diversity of the accordion, he knew even before finishing school and gaining numerous prizes, that he would choose to continue his passion in a professional manner and began to study at the University of Music FRANZ LISZT in Weimar with Prof. Claudia Buder. In 2021, he won the first prize of the renowned international accordion competition in Vilnius, which is his most important personal 
achievement.

Daniel Roth, born on January 19th, 1997, in Neunkirchen (Saar), started his musical education on the accordion at the age of 9. Since then, he has become a laureate of various national and international competitions. Participation in masterclasses and numerous concerts took the young artist to several countries across Europe. His musical and social engagements receive recognition and support by several scholarships including „Live Music Now” funded by the Yehudi Menuhin Foundation and the „Deutschlandstipendium”. 
With being inspired by the very specific sound and possibilities of his instrument, Daniel Roth’s path eventually led to Weimar, where he continues his studies at the University of Music FRANZ LISZT with Prof. Ivan Koval and Prof. Claudia Buder. Interested in modern improvisation and music theory, he traveled to Helsinki, Finland to take a year abroad at the Sibelius Academy with lessons from Prof. Veli Kujala.
