Sem is a composer, multi-instrumentalist, and software developer whose artistic practice explores the boundaries of aesthetics, sound, and perception. Deeply rooted in DIY culture and the traditions of Western contemporary as well as improvised music of the 20th century, their output spans solo performances, chamber and orchestral compositions, raw noise music, and multichannel media works, all underpinned by an interest in algorithmic processes, interactive and expressive systems.
Sem’s current artistic research focuses on
machine listening
can machines hear? lore ipsum and so on and so on, there will be more here soon!
non-human creativity
holysemiotics and human-non-human co-creativity – more soon
autonomous musical agents
what is an autonomous agent – same here, not much going on so far!
metamodern aesthetics
how to write music in the 21st century, say whaaaat? there will be more here as well! Promised!
