Larsp composes experimental electronic music. In 2002. His first project under the name of PUPPET LE CURE, sounds like hard-techno vs. melodic orchestra, and an EP was signed by independent label CWK in 2002.

His solo project under LARSP was launched in 2005. It follows a radically different approach from Puppet le curé. Larsp has moved away from techno to shift from experimental ambient to melancholic breakcore. The project is based on the atmospheres rather than dance floor, half-way between darkly oppressing sounds and slow rhythmic destructuring.
