Harmonic Frequency is a psychedelic electronic music project from Dutch producer Stefan Oldehinkel (9 may 1989). At the age of 18 Stefan started experimenting with electronic music, and a couple of years later Harmonic Frequency was born. // Some big musical influences are the early work Shpongle and Ott, but over the years Stefan developed his own distinct sound for the project. By deep sub-basses, hypnotic melodies and calming atmospheres the perceiver of the sounds is invited to go within, but also dance a little every now and then. // Harmonic Frequency is all about spreading good vibes trough music.
