"If I were to call myself a producer or an engineer, I'd likely be visited by the erinyes later in the evening," said Mroczek. "Suffice to say that I've been working on the composing and recording of music for a long time. Some of it sounds better than it should."

Credits include musical contributions and sound engineering on the avant-metal Bornwithhair albums Smole​ń​ska, Someplace to Haunt, and When the Witches Fall and the vampiric black metal Vinterdracul albums The Murnau Nocturnes and The Lee Variations. 

His production and songwriting can be heard on the Evil Will Bless EPs — And the Gods Shook and Uriel Spake Plainly. He performs with multiinstrumentalist Dirt Boucher and drummer Rick Morerick in the latter day Heavy Metal band Mephistophilizer. And he composes for and performs on his primary instrument — synthesizer — under the name Towerhouser. 

Late in 2024, he began recording ambient synth and techno with Apples Appleton under the project name Bicycle Deck. The duo put out two releases.

How the Disappearance Appeared to Us — his collaboration with Weirding Batweilder and Dirt Boucher was released in late 2024 under the band name Bleak Magician. This band has now become Srogi's primary recording vehicle — their second album, No Fireball Show, was released in May 2025.

Srogi also writes for and edits the zine Mephistophilizer (named after the band).
