PETDuo — Anne Gelfei and David Elie Merlino

03Legacy

Built in the
underground.

PETDuo are Anne Gelfei and David Elie Merlino, partners in life and music. Formed in São Paulo in 1997 and based in Berlin, they have developed a raw, physical approach to hard techno and schranz.

Their history runs through Love Parade, Time Warp, Awakenings, Tomorrowland, Defqon.1, Monegros and Nature One, alongside a current chapter that includes DGTL, Rave The Planet, Verknipt and MAYDAY Poland. Long before hard techno’s current wave, PETDuo were already building their own language within it. Today, they carry that history forward through a four-deck performance in which tracks are layered, cut and rebuilt live.

From their Berlin studio, Anne and David run Cause Records, their independent platform for hard techno and schranz since 2008. Together with Miss Djax, they created PET Trio and released the schranz classic “Dance or Die”. Their catalogue includes remixes for The Horrorist, Mario Ranieri and D.A.V.E. The Drummer’s “One Night in Hackney”, alongside PETDuo remixes by Svetec and Boris S. The principle remains unchanged: machine music with heart and soul.

    +FAQ

    Frequently asked
    questions.

    Are PETDuo available for worldwide bookings?

    Yes. We’re based in Berlin, Germany, and perform internationally across Europe, Asia, the Americas and beyond.

    For booking enquiries, please contact our official representative, Nature Bookings, or use the booking enquiry form.

    All bookings are subject to availability.

    What set lengths are available?

    Our performances typically run for 60, 90 or 120 minutes.

    We also offer extended three-hour sets and all-night-long performances. Set lengths and special formats can be arranged depending on the event.

    Why do PETDuo perform on four decks?

    We started out playing back-to-back on two turntables during the vinyl era.

    Inspired by artists experimenting with four turntables and two mixers, we began developing a format in which we could both perform simultaneously, layering tracks and shaping the music together rather than simply taking turns.

    This eventually became our signature performance setup.

    Over the years, we performed with four and even six decks, using two mixers. As DJ technology evolved, we streamlined the setup to four CDJs and one mixer without changing the concept behind our performance.

    Two DJs. Four decks. One continuous musical dialogue.

    Where can I download PETDuo’s EPK, press photos and technical rider?

    Our official EPK, promotional photographs and technical rider are available in the Booking / EPK section of this website.

    Where are PETDuo originally from?

    We’re originally from São Paulo, Brazil, where PETDuo was formed in 1997.

    We’ve been living and working in Berlin, Germany, since 2006, bringing our Brazilian underground roots into the international hard techno and schranz scene.

    Are PETDuo really married?

    Yes, we are!

    We met in 1994 at Hell’s Club, a pioneering techno after-hours party in São Paulo, and got married at the same venue in 1995.

    But we’ve always counted our story from the day we first met.

    Techno brought us together. It was love at first beat.

    How did Anne and David meet?

    Our story began at Hell’s Club, a pioneering techno after-hours party in São Paulo. David was a regular, and Anne was the hostess, taking care of the guest list.

    That venue became part of three important chapters in our lives: we met there in 1994, got married there in 1995, and performed there together as a DJ duo in 1997.
