Hi, I am Mat and my adventure with extreme vocals and singing began in 2012 when, fascinated by the skills of death and black metal vocalists, I decided to try my hand and check if I too could master producing similar inhuman and brutal sounds!

When I was taking my first steps as a vocalist, it was extremely difficult to find reliable, effective and safe methods for developing extreme vocal techniques.

After watching dozens materials on YouTube I felt even more lost and tired. I decided that I would embark on a journey through the world of extreme vocals on my own and using the trial and error method, sometimes painful, I would figure out what really works, what is effective but also safe for the voice, and what should be avoided like the plague!

That's when I also decided that when I was ready, I would create an effective and safe exercise program so that no one else would have to go through the same shit I did.

Everyone will gain proven knowledge and methods to improve their voice right now, without wasting time, without nerve-wracking and without risking damage to the vocal folds!

That was many years ago.

Now even beginners I train with are able to make better progress in three months than I did in over a year and a half of experiments and bouncing from one YouTube video to the next. All thanks to receiving a ready-made and proven action plan and avoiding all the mistakes and traps that most beginner extreme vocalists fall into.

Since 2017 I have run the YouTube channel "Sibila Extreme Vocal", through which I share simple and proven ways to master extreme vocal techniques from the ground up, such as fry scream, false chord growl, guttural, pig squeal and singing with distortion.

In addition to publishing materials, communication with viewers is very important to me - I try to respond to every comment in the most detailed and valuable way possible.

At the end of 2017 I was hired by the Polish Theater in Poznań - the longest running theater in Poland, operating since 1875 - to "train" a group of professional actors for the "K." play in the field of safe screaming. It was quite a challenge, because we only had a few weeks.

Despite the short time and many more important duties, the actors performed phenomenally on stage without losing their voice, captivating audiences again and again for a couple of weeks in row.

Since 2018, I have been conducting extreme vocal workshops around Poland, among others at Konador's School of Singing and Voice Emission in Warsaw (Nergal from Behemoth and many other popular Polish singers took singing lessons there).

I am also an active vocalist with thirteen recorded albums, several EPs, many singles (including bands like Vishurddha, SoulCarrion, Athvarf, Lyktgubbe, Imperial Sin, Moonthoth, Mardom, Algol, ZØRZA, Inrae, p53 - The Ascending Path) and dozens of shows all over Poland.
