Klaas - Heartbeat (official: Video Hd)

Klaas utilizes his trademark distorted saw-wave lead. It’s aggressive, side-chained heavily to the kick drum, creating a "pumping" effect that became the blueprint for much of the EDM that followed in the early 2010s.

While Klaas is perhaps most famous for his remix of "Infinity 2008," "Heartbeat" solidified his status as a solo producer who could command a dance floor without relying on a legacy sample. It captures a specific moment in electronic music history where the genre shifted from the smooth loops of 90s house into the aggressive, "maximalist" sound of the digital age.

"Heartbeat" by is a definitive example of late-2000s electro-house, specifically leaning into the "hands-up" and "fidget" influences that made the German producer a global club staple. Released during the peak of the "Klaas Style"—defined by jagged, saw-tooth basslines and high-energy percussion—the track focuses on a relentless, rhythmic drive rather than complex melodic progression.
