Adam Brass, operating under the moniker Internal Explorer, is a Warsaw-based techno producer and mixing engineer who integrates technical precision with raw underground aesthetics. He is a primary contributor to the Trainspotting Events collective, where he performs at unique industrial locations like PKP Praga and secret warehouses across Poland. His performance history includes notable appearances at the Wisłoujście and Undercity festivals, alongside regular bookings at prestigious clubs like Smolna and Ciało. A recent success is his Ambient Sundae series on SoundCloud, which allows him to explore experimental soundscapes outside of high-impact dancefloor environments. Brass frequently collaborates with artists like Michal Macewicz and Absvrd in back-to-back performances and offers professional mastering services under his own name. During the winter, his focus shifts toward the Polish mountains where he documents his interest in skiing, a lifestyle element that balances his late-night studio sessions and music production workshops for emerging electronic artists.
