From his musicological work, Schwerdt identified the challenge facing contemporary museum practice in relation to the "reinvention of the drum set combination" as they are "in European improvised music" of the 20th century became reality.

"Drummer, percussionist and artist Julian Sartorius forms sounds into previously unseen shapes. His precise and multi-layered rhythmical patterns are keen excursions into the hidden tones of found objects and prepared instruments, bridging the gap between organic timbres and the vocabulary of (experimental) electronic music. Julian Sartorius has released numerous solo albums, creates audiovisual art works, collaborates with musicians, writers and artist and performs live in intimate venues and on festival stages.

Trained at the Jazz schools in Berne and Lucerne by instrumentalists like Fabian Kuratli, Pierre Favre and Norbert Pfammatter, Julian Sartorius soon developed a singular musical approach. Being interested in fine-scaled variations, tension and release, mass and vibrancy, he creates projects like the 12-LP-box set "Beat Diary" (Everest Records, 2012), consisting of 365 beat tracks and an accompanying photo book; the daily 8-seconds loop series "Morphblog" (from 2013 to 2019); or "Depot", an audiovisual installation for 16 loudspeakers and 16 screens that was shown at Kunstmuseum Thun. For his last album "Hidden Tracks: Basel - Genève" (Everest Records, 2017), Julian hiked over 200 km with his drum sticks and recording equipment, playing and recording a multitude of sounds and textures on objects found on the journey.

In recent years, Julian Sartorius has collaborated with numerous musicians including Sophie Hunger, Sylvie Courvoisier, Gyda Valtysdottir, Dimlite, Shahzad Ismaily and Dan Carey. His distinct percussion work is featured on the current albums of Kate Tempest, Matthew Herbert and James Zoo.

Julian Sartorius has toured and performed live in North and South America, Asia and in Europe sharing the bill with artists like Marc Ribot, Deerhoof, Faust, Jaki Liebezeit and Arto Lindsay."
