is a Danish drummer, composer and bandleader based in Copenhagen.
 

With a background in jazz and improvised music, Sommer works across a wide range of musical styles, from acoustic jazz and free improvisation to electronic music, groove-based projects and larger ensembles. He is active both internationally and on the Danish music scene, performing and recording as a bandleader and sideman.
 

As a composer and bandleader, Sommer creates projects bringing together musicians from different generations and musical backgrounds. Improvisation and close musical collaboration are central to his work, particularly the ways in which musicians influence each other and shape the music together.
 

In 2024 and 2025, Sommer released The Nordic Trilogy on April Records. With the release of As Time Passes in 2024, he "shot to international attention", as one reviewer put it.

The trilogy received numerous five-star reviews, while As Time Passes was named one of Presto Music's Jazz Recordings of the Year in 2024.

​

His work has drawn considerable attention from international critics, who have described him as "a revelation", "a master of textural exploration at the kit", "a highly accomplished and empathic drummer" and praised his "wonderful touch on all elements of the kit". His drumming has also been described as being "in a class of its own" by Danish critics.

​

Alongside his own releases, Sommer continues to compose, perform and record across genres, developing new projects and collaborations.
 

He holds a Master's degree in Music from the Royal Academy of Music in Aarhus and the Sibelius Academy in Helsinki, as well as an Advanced Postgraduate Diploma (Soloist) from the Danish National Academy of Music (2022).
