With a musical background in classical piano, Régis Baillet never ceases to enrich his ranges, driven by a curiosity for sounds which leads him, for example, to the  practice of Dhrupad singing under the Dagar’s tradition. He claims these musical influences, classical music and modern classical, as well as sacred music from all the tradtitions and currents of modern music : IDM, drone, glitch, ambient, industrial, dubstep, microsound, post-rock, spectral music…

Some tasteful critics characterize his musical style as constantly evolving. Régis Baillet proceeds in his compositions by accumulating layers and sounds revealing a sensitive music, with melancholic and contrasting atmospheres.

In 1991, he created the electronic music duo Ab ovo with Jérôme Chassagnard and recorded several CDs as so many innovative auditory experiences.
