What clients say
In their own words.
I have been working with Henri (Cid Inc Mastering) for all of Tronic’s releases as well as all of my own productions and am VERY happy with his work! I have worked with many of the top mastering houses (Exchange, Masterpiece etc.) and can assure you that Henri is one of the best when it comes to house and techno music.

We have found CID INC to be a very reliable and timely service, for Octopus Recordings and the Black label. Henri constantly delivers the highest standard masters around.

About
I'm Henri Hurtig, also known as Cid Inc.
I’ve produced, mixed and mastered club music for over two decades. Today I master releases for labels like Tronic, Hope Recordings and Anjunadeep, and for artists including Nick Warren, Christian Smith and Guy J.
Every master is done by me, start to finish. If something needs a closer look, you’ll hear it from me directly.
