Komplexika is the latest Drum +Bass release from Colorado based artist/producer/audio engineer Jonathan Loeser, a/k/a INVALID. A established musician and an avid professional drummer, INVALID exhibits organic skills on the drums that shine through while listening to his latest effort, blending both organic and electronic sounds. With a obvious seasoned approach, you can hear the layering of soundscapes onto mechanical beats; these serve as the foundation upon which each track earns enough style and substance to stand on its own. These songs are composed with musical melodies that rely on the underbelly of filthy bass lines and textured sounds. These aspects give a cinematic quality that clearly aches to add a visual journey to the audio experience. When I close my eyes and the first track, Shadow Sphere, plays, the synth sounds are so textured that if I could touch them, I know that they would feel warm and fuzzy, bouncing like elastic under my fingers. Wow, this is really animated sound! The way that the drums hit your ears is addictive, and the beat holds your attention and drive the song from start to end…so precise and on point. If you love the drums as much as I do, then wait till you drop track three in your decks. Rise To Me is the Tech DNB sub-genre side of the EP, with beats that I will refer to as sonic in their sound, and progressive in the way they feel. INVALID employs a deliberate approach, clearly drawing on his decade of professional stage time as an organic drummer, while using the multiple skins available in his kit to change tone, texture and color within the songs structure, giving the beats a natural ability to carry the entire weight of the tracks body and soul. It is important to highlight, in the spirit of giving this EP a thorough review, the way in which INVALID validates the honesty of each song’s beginning and end. There are three parts to producing and performing every track on this EP. There is the intro, followed by the body, and of course thee end. I always say to my girlfriend and editor the difference between a DJ and a producer is vast. When a musician writes and performs from a classically trained background, he or she brings skills to the dance that others who simply push play don’t possess. In this case specifically, INVALID has a decade of organic musicianship in his wheelhouse that enables him to compose, layer and produce something different in both a genre and a time where being original and authentic is rare. In closing, to allow you, as the listener, to engage and enjoy the complete experience that this release has to offer, I would suggest headphones or taking an after midnight drive so that it is just you and the music. I believe that you will not come away without having the this musical journey surprise and enlighten you as you take the long way home.
