Deeply Mysterious Drone - C - 80 Bpm

Indie music maker, available for sound design & music for media.

I grew up with music & technology, and I love them both.
I love many genres but rock and electronic music have a special place in my heart.

Why the name Dark Side of Synth? Because it’s cool and it sums up my fascination with the dark side and with synthesizers. Dark side not just as negative but also as obscure, unknown, unexplored...

Don’t worry, you won’t be finding only darksynth, heavy, scary and sad tunes and tones here but quite a wide range and lots of happy, upbeat things too. Again, it is just a name – not a mission statement set in stone forever.
