Filian alias stays for Fill Ryabchikov - electronic music producer and digital artist.
Arisen from Russian Saint Peterburgs garage-rock scene, previously known under the alias Overbolds, this certainly promising electronic music producer benefits vastly from cross-genre inspirations. EDM , retro-pop, indie rock or anything in-between is nothing unfamiliar to him. Put all of this together with raw rocker's attitude and as an outcome you'll get a pretty good definition of Filian's style.
As for illustrations - it is a mix of sci-fi, retro-futurism, and colorful pop-art.
