Behind the Synth-Pop Waves: The Story of Stereo, Haloo Helsinki!’s High-Profile Electronic Alter Ego
When one of Finland’s biggest pop-rock titans, Haloo Helsinki!, announced a well-deserved hiatus in 2018, fans wondered what the band’s core creative masterminds would do next. The answer materialized in the form of Stereo (stylized as STEREO), an electronic dance music (EDM) and synth-pop duo formed by guitarist Leo Hakanen and lead guitarist Jere Marttila.
Far from a simple side project, Stereo became a fascinating masterclass in reinvention, proving that Hakanen and Marttila’s songwriting prowess extended far beyond stadium rock guitars into the glittering, nocturnal world of modern electronic production.
The Genesis of a Secret Sound
Haloo Helsinki! had dominated Finnish airwaves and arena stages for over a decade, leaving a massive cultural footprint. Seeking a fresh creative outlet during the band’s break, Hakanen and Marttila pivoted sharply toward electronic music.
Operating under the moniker Stereo, the duo stripped away conventional rock instrumentation to experiment with heavy basslines, infectious synth melodies, and contemporary club rhythms. Rather than flying completely under the radar, they chose to embrace a collaborative spirit, treating Stereo as an open canvas for a revolving door of prominent Finnish guest vocalists and artists.
00740: The Breakthrough Album
In 2019, Stereo dropped their debut and defining studio album, 00740, a release that quickly captured the attention of mainstream pop and club audiences alike. The album showcased the duo’s sharp ear for crossover hits, merging slick electronic production with deeply catchy vocal hooks.
The project spawned several high-charting singles that dominated Finnish radio and streaming platforms:
- “Vuosien päästä” (featuring rapper Etta) — A melancholy yet driving electronic track that became a massive streaming success.
- “Sä saat mut palasiksi” (featuring Samu Haber) — A powerful collision of Haber’s raspy, stadium-ready vocals and sleek synth-pop soundscapes.
- “Woo Woo” (featuring rock legend Michael Monroe) — A high-energy, eclectic track that bridged Monroe’s punk-rock attitude with futuristic electronic beats.
- Additional collaborations with artists like Aste, Sini Yasemin, and Ida Paul & Kalle Lindroth cemented the album as an all-star showcase of modern Finnish pop talent.
Legacy and Cultural Impact
Though Stereo was primarily active during Haloo Helsinki!’s 2018–2019 hiatus, the project left a lasting impression on the Finnish music scene. It demonstrated how established musicians can successfully pivot across genres without losing their distinct compositional identity.
For fans of Haloo Helsinki!, 00740 offered a thrilling glimpse into the production minds behind the band’s biggest anthems. For electronic music enthusiasts, Stereo stood on its own as a brilliantly curated, collaboration-heavy celebration of Nordic pop craftsmanship.
Though its run was brief, Stereo remains a shining example of creative reinvention—proving that when great songwriters change the rules of their craft, the results are bound to echo across the dancefloor.
