Looking for a vocalist for prog metal project (Amsterdam)

Hi everyone! We are 3 musicians in the region of Amsterdam, looking to complete our starting progressive metal project.We currently rent sessions of 3h in studios in Amsterdam (JamStudios or Q-Factory), but would consider renting a more permanent space once the band is more complete.

Who we are:
Remmert: drums, likes The Dillinger Escape Plan, old school death and black metal, making trap beats...
David: bass, likes BTBAM, Pain of Salvation, black metal classics...
Nicolas (writing this ad): guitar, likes Haken, prog, from 70's classics to modern metal, some classical and jazz pieces, or a good OST, just crank up the drama!

To give you a clearer idea, you can listen to our current demos. Vocals are by me, I'm not too unhappy about them, but they are mostly to show what I have in mind. Obviously a proper singer could take those lines to a much better level!

In the links below, you can listen to more of my solo material.

What we're looking for:
Someone with enough skill to carry the vision, able to deal with complex song structures and to match the intensity of metal music. Ideally someone who can do clear and harsh vocals, but the priority goes for clear ones.
On the other hand we're not necessarily looking for a power metal tenor, and we prefer technique over big vocal range.

If you have more questions, feel free to message me.
