My name is Hannes Grossmann from Germany. I'm a professional session drummer & studio engineer (recording, mix and master).

My studio is called "Mordor Sounds" and can be visited at

I play drums for more than 20 years and have played with bands such as Necrophagist, Obscura, Blotted Science, Hate Eternal and currently play drums in Alkaloid. I have played on many recordings, mostly of underground music artists. Even though my own bands could be tagged as "metal" I cover pretty much every style. I also write my own music and play guitar and piano.

The way I usually work is that I receive one or several songs, work out a drum line, record it, edit the drums (if necessary) and send out individual tracks. Of course I make as many changes as the customer wants - until every customer is 100% happy.

I have an own professional recording studio called "Mordor Sounds", which makes session work easy and allows me to work for customers around the globe. I already did drum session work for people in the US, Canada, England, Mexico and even Pakistan - without even leaving the house.

I also record and mix other bands and artists, which is my passion and profession. Feel free to check out my studio at My rates are very reasonable.

I'm endorsed by Meinl Cymbals, Tama Drums, Evans Drumheads, Vic Firth Sticks and Rode Microphones.
