Oscar Mulero is Techno House CDA Magazine’s Artist of the Month for September 2026, celebrating one of the most enduring figures in Spanish techno and an artist whose career has been deeply connected to the development of Madrid’s underground electronic music culture.
From the early days of Spain’s techno movement to the international underground, Mulero has spent decades developing a sound defined by precision, atmosphere, hypnotic rhythm, and uncompromising dancefloor energy.
In September 2026, another chapter was added to that story with the release of his new studio album, Between Two Worlds, on Semantica Records.
A Career Built Around Techno
Oscar Mulero’s relationship with electronic music began during the formative years of Madrid’s club culture.
Over the decades, he became closely associated with the development of Spain’s techno scene, moving through different stages of the culture while maintaining a strong focus on underground music.
His career has never been limited to one particular interpretation of techno.
Across his productions and DJ sets, Mulero has explored hypnotic rhythms, industrial textures, atmospheric passages, experimental electronics, and powerful peak-time structures.
The result is a musical identity that has remained recognizable while continuing to evolve.
From Madrid to the International Underground
Madrid has played a central role in Mulero’s artistic story.
His work became part of a generation that helped establish techno as an important part of Spanish electronic culture, while his performances and productions eventually reached audiences well beyond Spain.
His influence can be felt across the European techno scene, particularly through his work as a DJ, producer, label founder, and curator.
Rather than simply following the evolution of techno, Mulero has been part of the process of shaping it.
Warm Up and PoleGroup
Mulero’s contribution to techno extends beyond his own productions.
Warm Up Recordings became an important platform for his music and artistic vision, helping establish a distinctive sound connected to the Spanish underground.
Later, PoleGroup developed into another major part of his work, creating a home for forward-thinking techno and artists working across darker, experimental, and hypnotic territories.
These platforms reflect an important characteristic of Mulero’s career: the desire to build a scene rather than simply participate in one.
Through his label work and collaborations, he has helped introduce audiences to a wide range of artists while continuing to develop his own musical direction.
Between Two Worlds
September 2026 brought a major new release from Mulero.
Between Two Worlds presents a collection of new productions that continue his exploration of techno while allowing space for atmospheric and experimental electronic elements.
The album moves through dark textures, hypnotic rhythms, industrial tones, and carefully constructed sound design.
Tracks such as “Footprints Behind Fear,” “Lost Verses in You,” “Broken Horizons,” “Invisible Chains,” “Beneath the Surface,” and “Shadows Between Us” create a journey through different shades of Mulero’s musical identity.
Rather than functioning simply as a collection of club tracks, Between Two Worlds feels like a complete electronic journey.
A Different Kind of Techno Journey
One of the defining qualities of Mulero’s music is its sense of movement.
His tracks are often built through gradual development rather than relying exclusively on immediate impact.
Rhythmic layers accumulate.
Textures appear and disappear.
Atmosphere becomes part of the percussion.
The result is music that can work inside a club environment while also rewarding listeners who approach it as a deeper electronic listening experience.
Between Two Worlds continues that approach.
The album moves between different tempos, moods, and structures, creating a listening experience that feels broader than a conventional collection of dancefloor tools.
The Dancefloor Remains Central
Despite the experimental and atmospheric dimensions of his music, Mulero’s work remains deeply connected to the physical experience of techno.
His DJ sets are built around tension, progression, repetition, and atmosphere.
Rather than depending on individual moments, the experience develops gradually, creating a continuous journey for the dancefloor.
This approach has helped make Mulero one of the most respected names within underground techno while allowing his performances to remain relevant across different generations of club culture.
The Importance of Longevity
Electronic music changes quickly.
New sounds emerge, new artists appear, and club culture constantly develops new directions.
Mulero’s career offers a different perspective.
His work demonstrates how an artist can remain connected to underground techno across multiple generations without abandoning the core principles that shaped his sound.
Instead of following every change in electronic music, Mulero has continued to develop his own musical vocabulary.
That consistency has become one of the most recognizable aspects of his career.
More Than a DJ
Oscar Mulero represents several different roles within electronic music.
He is a DJ.
A producer.
A label founder.
A curator.
And an important figure in the history of Spanish techno.
His influence can therefore be understood not only through individual tracks or performances, but also through the networks, labels, artists, and audiences that have developed around his work.
That broader contribution is particularly relevant at a time when underground techno continues to expand internationally.
A New Chapter After Decades in Techno
Between Two Worlds arrives at an interesting point in Mulero’s career.
Rather than presenting a dramatic departure from his established sound, the album continues a musical conversation that has developed over decades.
The record brings together driving techno structures, electronic atmospheres, and carefully constructed sound design across its tracks.
For listeners discovering Mulero for the first time, the album offers an introduction to his current sound.
For longtime followers, it represents another stage in an artistic journey that continues to evolve.
Why Oscar Mulero Is Artist of the Month
Techno has always been about evolution.
Its most enduring artists are often those who understand the history of the genre while continuing to explore what can come next.
Oscar Mulero’s career reflects that balance.
His connection to Madrid’s early techno culture, his work through Warm Up Recordings and PoleGroup, his extensive production catalogue, and his continued presence in international clubs have made him a distinctive figure within the underground electronic music landscape.
With Between Two Worlds, September 2026 offers another opportunity to experience that artistic vision.
The album demonstrates that techno does not need to abandon its foundations in order to evolve.
It can become deeper, more atmospheric, more experimental, and more expansive while remaining connected to the rhythm and energy of the dancefloor.
