The “Girl-Coded” Industrial Revolution: Who Are EQ, Estratosfera & Qiri?
By [Your Name/Platform Name] Published November 29, 2025
In the smoky, strobe-lit basements of Buenos Aires, a new sonic architecture is being built—one that is equal parts “utopic hot pink” and industrial grit. EQ, the electronic duo formed by Argentine producers Estratosfera and Qiri, has rapidly ascended from local underground secrets to global electronic contenders.
With the release of their defining debut EP EQ by EQ in late 2025, the pair has solidified a sound that defies easy categorization—blending the aggression of techno with the gloss of hyper-pop. This biography explores the origins of EQ, the contrasting musical DNA of its members, and their meteoric rise in the Latin American electronic circuit.
The Formation: A “Girl-Enhanced” Vision
EQ is more than a musical collaboration; it is a conceptual project born from the desire to reclaim space in a male-dominated industry. Formed by Laura Ferreira (Estratosfera) and Candela Mattera (Qiri), the group emerged from a shared ambition to create a “girl-enhanced” universe where technical prowess meets aesthetic frivolity.
The duo describes their dynamic as “complementary opposites.” They initially bonded over a shared love for “weird music” and a vision to merge the digital futurism of the PC Music movement with the raw energy of Buenos Aires nightlife.
“We are girls who want to have fun, but we are music nerds before that,” Qiri stated in a 2025 interview. “Our sound is harsh, but attractive—electronic and futuristic with a nostalgic touch.”
Meet the Members
The magic of EQ lies in the friction between the members’ vastly different musical backgrounds.
Estratosfera (Laura Ferreira)
Before commanding dancefloors, Estratosfera (Laura Ferreira) was a staple of Argentina’s alternative rock and shoegaze scenes. She first gained recognition as the guitarist for the band Nenagenix and the artist Saramalacara.
-
Musical Roots: Her transition to electronic music was driven by a desire to fuse her “punk” ethos with digital synthesis.
-
Solo Work: She released a solo album titled 1, which laid the groundwork for her industrial-pop hybrid style.
-
Role in EQ: Often described as the textural architect, she brings a distorted, high-energy edge to the group’s production, focusing on the “kick drum perfection” that drives their tracks.
Qiri (Candela Mattera)
Qiri (Candela Mattera) acts as the “academic foil” to Estratosfera’s rock-oriented approach. A former classical piano student and music college dropout, Qiri grew up composing songs and feeling confined by traditional academia.
-
Musical Journey: Feeling stifled by the conservatory, she pivoted toward experimental computer music, searching for sounds that broke the rules of standard composition.
-
Role in EQ: Qiri brings a structural, melodic sophistication to the chaos. She is often responsible for the lead synth lines, using her background in composition to create catchy, pop-adjacent melodies that float over Estratosfera’s heavy beats.
Career Highlights & The EQ by EQ Era
The year 2025 marked EQ’s official breakthrough. After building anticipation with singles throughout 2024, they released their self-titled debut EP, EQ by EQ, in September 2025 via the label Fractura.
Key Releases:
-
“Boytoy” (2024): Their debut single was an immediate statement of intent. Critics described it as “Crystal Castles gone reggaeton,” featuring heavy basslines paired with ethereal, detached vocals.
-
“EQetamine” (feat. MAJA & OKTE): A high-octane club anthem that showcased their ability to collaborate with other heavyweights of the local scene.
-
“Girls My Age” (2025): A standout track from their EP, accompanied by a music video that highlights their signature “early 2000s digital” aesthetic.
-
Remix Work: In late 2025, they released “TWELVE is BOLD,” a remix of Shygirl’s track “TWELVE,” further cementing their status on the international radar.
Live Performance & Aesthetics
EQ has become synonymous with a specific visual identity involving shiny acrylics, wired headphones, and Y2K tech. Their live sets—including a notable performance at the HÖR Buenos Aires Pop-up in March 2025—are theatrical experiences that blend DJing with live vocal performance, proving they are as much visual artists as they are musicians.
Unique Facts
-
The Name: “EQ” (Equalizer) is a nod to their roles as audio engineers, asserting their technical authority in a field that often overlooks female producers.
-
Complementary Workflow: In the studio, they split duties strictly: Estratosfera often handles the rhythm and texture, while Qiri focuses on melody and arrangement.
-
Global Ambitions: While deeply rooted in the “post-crisis” creativity of Buenos Aires, the duo has expressed clear intentions to tour European capitals like Paris and Berlin by 2026.
