During his musicology studies in Cologne (with majors in composition and electronic music), Schmickler initiated “a-musik” with friends, in 1995: to this day a worldwide outstanding experimental music construct comprising a record store, distribution and label, managed by Georg Odijk.
In the mid-1990s, Schmickler also founded his post-rock solo project Pluramon (released on Mille Plateaux and Karaoke Kalk) proving his claim as a musician across genres early on. Schmickler’s work references the influential German electronic music tradition, French spectral music, American experimental and noise music, as well as club music in general. Schmickler’s music is characterised by harmonious colours and microtonal moods, engaging in a forward-looking discourse about algorithmic techniques during sound production.
Most of Schmickler's music is designed for multi-channel sound projections. His oeuvre includes numerous sound installations specifically created for a site, interdisciplinary works (crossing into film and lighting art) as well as artistic collaborations (with theatre director Felix Ensslin and visual artist Gerhard Richter).
Marcus Schmickler runs the electroacoustic studio Piethopraxis, in Cologne.
