If you want your project to have a professional sound, don’t hesitate to contact me!


I strive to be a sound technician and producer worthy of 2021 and match the high demands in modern quality of music and audio production. But still with respect and elements from the previous audio and music heritage.


I have been a musician for ten years and through my music I have gained experience and a deep understanding of taking on someone else's idea and artistic vision. There is nothing more fun than to shape a professional recording to its full potential in the mix and production stage. 


My main genre is rock and metal but I also master other genres. I would describe my strength in a mix with words like modern and rich. 


I am genuinely interested in audio and production and always want to gain broader knowledge and understanding of it. My goal is to become the best version of myself and reach the top in the business. 


I play guitar in the band Nocean where I now record, mix, and produce all the music.


With accuracy and an aspiration for an "uncompromising sound" for the projects I’m taking on, I sincerely hope that I am the right person for your music.

Music producer/composer








Music has been my passion for my whole life and I am a multi-instrumentalist with a great ear for compositions. I have been a lead singer and composer in a metal band (Nocean) for 7 years, I've written music for Swedish television (SVT/UR) and I am also a podcast producer. When it comes to music productions my main knowledge is in the genres acoustic pop and melodic rock/hard rock/metal.


I can assist your production in following areas:

- Adding synthesizer arrangements/orchestral elements to your recording

- Vocal coaching during recordings or sending feedback on your already recorded tracks

- Adding professional vocals or backing vocals to your recording
- Podcast production/editing.

I am also the owner of a Swedish video production company: Blueline Post
