From the first beat, the energy hits instantly. Heavy, swinging percussion locks into a driving rhythm while a rolling low end builds unstoppable momentum. The groove feels alive, pulsing with the kind of underground energy that defined iconic Ibiza floors. Every sound is placed with intent, from the tight drums to the subtle FX that keep the track evolving throughout.
Where earlier instalments in the series leaned into disco, acid and electro influences, ‘Back To School 4’ ties everything together. It is functional and fluid, packed with weight and movement, yet full of character. STO’s signature production style shines through with clean percussion, punchy low-end and a precise arrangement that keeps dancers locked in.
The result is a track made for the club. DJs will find it versatile and powerful, ideal for driving peak-time sets or adding underground flavour to warm-up moments. Its hypnotic flow, tight groove and percussive depth make it a reliable tool for selectors who value rhythm and energy.
With this release, STO signs off the Back To School series on a high. Across four instalments, he has explored a wide palette of sounds and influences, from raw club tools to hybrid experiments. ‘Back To School 4’ serves as the perfect finale, a heads-down groover built to move crowds and celebrate STO’s evolution as a producer.
