The vinyl purist discusses his late-career ascent, the discipline of the marathon set and the shifting class dynamics threatening the underground.

In an era where the word "techno" is often used as a broad marketing catch-all, Alessio Armeni, AKA Freddy K, stands as one of the sound's most uncompromising activists.

The Berlin-based DJ and Key Vinyl label head has spent over three decades operating in every corner of the industry. From his early days on Rome's Virus Radio in the '90s to his legendary 16-hour vinyl marathons at Berlin's now-defunct party Homopatik, he has seen the culture from the perspective of a record store clerk, a distributor, a label boss and now a global headliner.

But as his own star has risen, Armeni has become increasingly vocal about the cracks forming in the foundation of the scene he loves. In this RA Exchange, he discusses the renewed normalisation of all-male lineups, the rising upper-class barrier to entry in DJ culture and the complex economics of vinyl—a medium he champions as the industry's lifeblood, even as it becomes a luxury good.

Armeni also reflects on his own trajectory; at 40, believing his dream of being a successful DJ had passed, he moved to Berlin to dedicate himself to a life behind the scenes. A change in tide swept him into the global spotlight, and more than ten years later, he contemplates the power of perseverance. Listen to the episode in full.
