Martin “Muudu” Kuut

Born in Tartu, Estonia, Muudu found freedom in music. Growing up in Estonia, he was surrounded by friends from different subcultures, listening and exchanging contrasting music genres. The experience of over 20 years playing keyboards and guitar in various bands, composing, and DJing for more than a decade made him go after more and relocate to Berlin to pursue studies at Abbey Road Institute. He has found his signature style of resonating duality where contradictions are balanced and flow in harmony, where every element makes sense and sounds. “Who Let The Bear In The Studio”, released by Moodmusic Records, is his first LP. In the future, Muudu will be revealing some more as part of the BlackheadStudios and Moodmusic family, a studio and label led by house music mastermind, DJ, producer, and genius mastering engineer Klas “Sasse” Lindblad.

Alberto Pretto

Alberto Pretto – Mastering Engineer (Blackhead Studios)

Alberto Pretto became interested in music at a very young age while listening to his father vinyl record collection. The  special bound with those black discs evolved itself quickly in very deep emotions while he was handling them, that much, that got him closer and closer to music and sound until he started mixing records in clubs when he was 16.

Being a Dj wasn’t just enough for Alberto, he wanted to produce his own music and that is what really made a significant turn in his career by eventually  having various releases after he moved to London in 2009.

The Italian born moved again in 2013 to Berlin and there he graduated in music production and sound engineering with a very distinctive result at the prestigious “Abbey Road Institute”. Abbey has been a very unique place for him where he met two of the most important mentors of his studies, like Klas Lindblad, which happens to be also his colleague and studio owner at “Blackhead Studios”.

Alberto’s finesse, focus and attention to details on sounds are the characteristics that got him noticed and also pushed his talent up in the rank of BHS engineers.

Since 2019 he’s established as engineer at Blackhead Studios, having the chance to master and collaborate with Klas for an amazing array of artists.
