The label was running by Roman "SMC PR" Paramonov and Andrey Burtaev aka ELECTROSOUL SYSTEM in 2006.
From the beginning the label was oriented on mellow and deep side of drum'n'bass - intelligent, atmospheric, liquid-dnb and more wider specter of breakbeat electronic, and with each release has tried to bring new sound in the genre. Not without a influences of the label, in the world drum'n'bass was formed sub-styles like techmospheric and psychedelic drum'n'bass. The label opened few new talents like Bop, Cutworks, Abstract Elements, Pryzma between others, and has given a notable push to development to a local Russian and ex-USSR (russian-speaking) scene.
In the period from 2007 to 2010 the label has released 10 vinyl releases, include 1 double and 1 triple vinyl samplers. Besides names resulted above on a label also were released artists as Future Engineers, Subwave, Logarithmia, Makoto, B Cloud, Mav, Purple Haze, Oak, Reborn and of course label frontman Electrosoul System.
Just in 2011 the label came out to world with digital editions of their backcatalog, that was unavailable in digital format before, and same time started to promote their new digital-only releases. Digital format has given more possibilities for release of more tunes and different remixes not only in drum'n'bass/breakbeat styles.
Kos.Mos.Music tunes have support from different big names of scene like LTJ Bukem, London Elektricity, Goldie, Fabio, John B, D-Brigde, Markus Intalex, Makoto and others.
