Guitarist & Composer
Born in 1994, guitarist and composer Gilles Grethen belongs to the young generation of Luxembourgish jazz musicians. As the son of two musicians, he inherited his musicality and began his classical music education at the age of 4. After small “detours” via the violin and the clarinet, Gilles Grethen discovered age 14 his passion for jazz and the guitar. He studied with Greg Lamy and Jacques Pirotton at the Luxembourg City Conservatory where he completed his studies in jazz guitar in 2015. In 2020, Grethen obtained a bachelor’s degree with Martin Schulte in jazz guitar at the University for Music Saar in Saarbrücken, and in 2022 a master’s degree with Jürgen Friedrich in jazz composition at the University for Music and Performing Arts in Mannheim. He is currently completing a master’s degree with Frank Kuruc in jazz guitar in Mannheim.
Besides his own jazz project, the Gilles Grethen Quartet, he also has the duo CHROMA with the German pianist Sebastian Voltz, plays with the renowned Luxembourg Little Big Band and the jazz fusion band Linq. The focus of his artistic work is on composing and arranging as well as the artistic analysis of other artists’ repertoires such as in projects with music by Kenny Wheeler or Kurt Rosenwinkel. Other projects of Grethen include the music for Catherine Dauphin’s short film “Coffee & Water” as well as compositions for the Luxembourg National Jazz Orchestra and the Opus78 Orchestra, both commissioned by the Ministry of Culture.
