PETDuo

PETDuo is a Brazilian electronic music duo comprised of Ana Luiza Gelfei and David Merlino, who began producing together in 1997.

The duo produces hard techno and peak time driving techno, releasing primarily through Riot Recordings and appearing on Curation Best Of 2025 compilations. Their sound sits firmly in the high-energy spectrum of electronic dance music, designed for peak-hour dancefloor moments and festival environments.
