In the late 1980s, as techno and house made its way around Europe, mutating as it hopped from city to city, one young DJ from Curacao made a mistake that would inspire a brand new sound. While he was performing at Den Haag's Club Voltage, DJ Moortje accidentally dropped a dancehall track at 45RPM rather than 33, and let it play out. Thirsty for a hi-NRG sound, the crowd loved the squeaky vocals and rapid beat, and bubbling (or bubbling house) was born.

For the next couple of decades, bubbling was a crucial part of Holland's Afro-diasporic club landscape. And as a new generation of wide-eyed young DJs and producers began to take the reins, it evolved accordingly. In the late-2000s, Den Haag-based teenage prodigy Guillermo Schuurman followed in the footsteps of his uncle DJ Chippie (one of the genre's co-founders) and cousins DJ Daycard, DJ Master-D, Stiko Jnr and DJ Justme, and began performing and writing beats. Using Fruityloops, he fused familiar bubbling rhythms with rap and R&B samples, trance synths and electro house wobbles, and his tracks quickly became a regular fixture on the Dutch circuit.

»Bubbling Inside« is a collection of Schuurman's most essential cuts from the era (2007-2009), with a couple of newer productions added for context. Crafted solely for the dance, most of these tracks were never properly released and have been painstakingly hunted down and collected by the Nyege Nyege Tapes together with Sascha Roth from Pantropical in Rotterdam and De Schuurman himself. Hearing them together highlights just how forward thinking the young producer was, steering a Dutch institution into the future.

2008's »First One« is a proto-Berghain belter, with booming bass-heavy kicks underpinning the kind of cheeky melodies that remain the calling card of the genre. »Pier Je Bil!!« ratchets up the tempo, twisting bubbling's syncopated dancehall kicks into a rapid-fire club clatter and decorating them with steel-pan melodies. Elsewhere, 2019's »Domina« shows how Schuurman's production style has developed as he mutates trap percussion, dubstep bass and eerie synth textures, while retaining the DNA of bubbling. »Bubbling Inside« is a testament to the evolution of the bubbling genre, as witnessed by one of its most visionary producers.
