-------------------------------------------------------

Although OSC is currently celebrating its 200th anniversary, this track was created for the 198th challenge – a small tribute to the series that nevertheless captures the groove of the anniversary energy.

With 92 BPM, catchy harmonies, a concise bass hookline, and crisp kicks, FractiQ takes you straight to the dance floor. The melodic fractals weave together into a catchy tune that sticks in your mind.

Perfect for all fans of melodic music, hypnotic chords, and pulsating energy.

NJoy. Any feedback welcome.
