Simon Løffler was born in Denmark in 1981. He began studying composition with Bent Sørensen, Hans Abrahamsen, and Niels Rosing-Schow, as well as music theory with Lars Bisgaard at the Royal Danish Academy of Music. He continued his composition studies with Wolfgang Heiniger at the Hochschule für Musik Hanns Eisler in Berlin, and with Simon Steen-Andersen at the Royal Academy of Music in Aarhus, Denmark. He then joined A.PASS, a research institute for advanced performance and scenography studies in Brussels. Since 2017 he has been a lecturer in composition at the Royal Danish Academy of Music.

Løffler’s work explores visual music and the visual arts. His pieces take the form of installations as frequently as they do instrumental music, for which he uses modified traditional instruments or reaches for new instrumental concepts, such as fluorescent light tubes, toy pianos, rudimentary synthesizers, or effects pedals. These lend his music a singular sound that sometimes approaches that of noise music, and often call into question the relationship between performer and audience, as in the work c (2013), which is written to be listened to with one’s teeth.

In 2014, Løffler was awarded the Stipendium Prize at the Darmstadt Ferienkurse für Neue Musik. In 2015, he was awarded a three-year work grant by the Danish Arts Foundation, following a previous prize from them in 2013.

His compositions have been performed by many ensembles, including Nikel, Asamisimasa, Scenatet, Adapter, Suono Mobile, Plus-Minus, Speak Percussion, Ensemble Pamplemousse, We Spoke, hand werk, Curious Chamber Players, Athelas Sinfonietta, Neue Vocalsolisten, and Defunensemble.

In 2019, his piece Dream work (2018), composed for the eponymous film by Peter Tscherkassky, was performed at IRCAM’s ManiFeste festival.
