“Blanket” is a short animated film about a blanket which is lost at a gas station, full of suspense and even some classic horror elements. Blanket was created by Nigh Lievaart (N-toons). Sem wrote the original soundtrack for this film.

The human psychology and its twists and turns have been the main inspiration for this piece. Joy, melancholy, struggle, triumph, many emotions have been adressed.

Laguna was commissioned by the Dutch Open Percussion Championships as the set piece for the entry class of the competition.

A piece for mezzo-soprano and piano on a poem by Elea Bekkers, performed by Elea Bekkers (mezzo-soprano) and Anne-Maartje Lemereis (piano). This was the first piece Sem wrote together with Elea, a collaboration which eventually led to art-collective STAATSGREEP.

“A Modern Day Scheherazade”, performed by 10 very talented cellists from the HKU Utrecht Conservatory. As part of a school project we had 3 days to rehearse a full program and the results were absolutely terrific. Even though the piece is called Scheherazade, it doesn’t necessarily depict the literal story of a thousand and one nights. More so the contrast between fragility and power within the story, and how those two ultimates can ever so quickly turn into each other. All my thanks go out to the cellists and to Joel Hoffman for his coaching.

“Dusk” and “After Dusk” are two a capella pieces I wrote for the Utrechtse Studenten Cantorij (www.uscantorij.nl), a wonderful choir which offers young composers the chance to write new music for choir. The pieces were written for their concerts going by the name of “Twilight Zone”. After I wrote “Dusk”, they asked me to write a sequel, which became “After Dusk”. Whereas “Dusk” is about the relative peaceful side of twilight, “After Dusk” is a take on the darkness of night in a more harrowing and percussive way.

“Toetsel en het Levenslicht” is a book written by Mike van Rossum which is now being developed into a motion picture animation film. I’m writing the soundtrack.
