What Is Hardstyle, Explained: The Netherlands Built It, and Jakarta's SIHK Brought It to Tomorrowland

If you've only heard one hardstyle track, it was probably loud enough to hurt. The genre runs on overdriven, distorted kick drums stacked against a bouncing offbeat bass, built for rooms that want a wall of sound rather than a groove. It's a world away from the deep house and minimal techno Loopliner usually covers, and Southeast Asia barely has a scene for it. But the region does have one genuine entry point: a Jakarta producer named SIHK who went from ghostwriting for Rich Brian to playing an all-Indonesian hardstyle set at Tomorrowland.

What Hardstyle Actually Sounds Like

Hardstyle sits in the harder end of the dance music spectrum, somewhere between hard trance and hardcore. According to Wikipedia's genre history, hardstyle's kick drum is what defines it: producers distort, equalize and layer it until it becomes a melodic, 'pitched' hit, usually paired with a reverse bass that lands on the offbeat. Early hardstyle sat around 140 BPM in the late 1990s. Modern productions run closer to 150 BPM. At that tempo, hardstyle and hardcore can sometimes sound indistinguishable.

Where Hardstyle Came From, and Where Its Biggest Stage Just Closed

The genre has no single inventor. It developed through the late 1990s across the Netherlands, Belgium and Italy, gaining its name and its commercial shape through Q-dance, the Dutch promoter that ran the first dedicated hardstyle event, Qlubtempo, in Zaandam in 2000, then trademarked the word 'hardstyle' in July 2002.

Q-dance's flagship show, Qlimax, grew into one of the genre's biggest annual gatherings: nearly 30,000 people a year at GelreDome in Arnhem, under a production rig of roughly 350 speaker boxes plus lasers and pyrotechnics. It ran for 24 years. On July 25, 2024, Q-dance announced that edition would be the last. Qlimax closed for good on November 16, 2024, under the theme 'The Final Prophecy.' If you wanted to see hardstyle at its most maximalist, in its country of origin, that specific door is shut.

Jakarta's SIHK Made It to Tomorrowland

Southeast Asia's clearest hardstyle story belongs to SIHK, real name Ricky Tjong, a Jakarta-based producer who started out fronting a metal band, taught himself production on a pirated copy of FL Studio, and later discovered rave culture during a stint studying in Seattle. He adopted the SIHK moniker at a Jakarta club night called Hide & Seek, a joke on the N95 mask he wore on stage, not long before he began producing for Rich Brian, then a teenager going viral off the 'Dat $tick' video. SIHK produced the beat for the track 'Who That Be' and later taught Brian the basics of FL Studio himself.

He met Jim from Yellow Claw in 2017, and Barong Family signed him soon after. His debut EP, 'Send Nudes', came out in 2018. The follow-up, 'Epic Side Quest', came out the year after. In 2019, SIHK played Tomorrowland with a set built entirely from tracks by Indonesian producers, telling fans beforehand he'd only play Indonesian-made music and later saying he was 'mind blown' that it was possible. He's also played Thailand's Siam Songkran, the regional cruise festival It's the Ship, and sold-out club shows in Japan and Taiwan.

From Hardstyle Into Something He Named Himself

SIHK's own sound didn't stay still. During pandemic lockdowns, he discovered happy hardcore through Australian producer S3RL while playing Animal Crossing, and pushed the tempo up to roughly 175 BPM, coining the term 'Hypercore' for the result. His four-track Hypercore EP came out on Barong Family on August 5. Its lyrics are unusually candid about depression and self-doubt, a sharp turn from the genre's usual euphoria. In 2023, that body of work got him signed to Dutch Master Works and then to Basscon, Insomniac's own hard dance label, where he debuted with the track 'Everything.' He has also been crowned Rising DJ of the Year for his home country. He was also one of 14 artists featured in Barong Family's 'Hard In Bangkok' album and documentary, filmed in Thailand in September 2019.

Where You Can Actually Hear Hardstyle in Southeast Asia

There isn't a hardstyle club circuit here the way there's a house and techno one. What exists is sporadic. Djakarta Warehouse Project has made room for the genre before, booking Da Tweekaz, Sub Zero Project and Kayzo for its 2023 edition. DWP's 2026 edition runs December 11-13 in Jakarta. As of this writing the announced acts skew trance (Cosmic Gate, Billy Gillies, MaRLo), techno (Lilly Palmer, Maddix) and mainstage EDM (Afrojack, Alok, R3HAB). Bangkok has its own small scene too: Hard In Zight, a dedicated hardstyle night, ran its third edition at AVVE Bar in March 2026. Outside of festival season and the occasional themed night, hardstyle in this region lives mostly on SoundCloud and in SIHK's own touring calendar abroad, not in a weekly residency anywhere.
