From day one Koen has always been more than just a standard sound guy. He's not only doing his job as a sound tech, he also tries to guide us as good as he can in order to have the perfect sound. With him behind the sound desk we feel double focused and safe because we know Koen will be keeping an eye on everything that could possibly go wrong. Ow yeah, he's also a pretty cool guy!

If you need a reliable and experienced sound tech who always goes to the bone in search for the best way to create the ideal sound, then Koen Keijers is your guy for the job. He gives the band exactly what the band wants and needs without pushing his own ideas. He's a very nice and flexible guy to work with and often comes up with his own ideas in order to optimize the band's sound. Very cool guy and a real pro!

Koen is one of the most enthusiastic foh sound engineers I have encountered. He brought me a different kind of vocal and guitar mic that he thought improved my sound and would suit me better. Very pro and nice dude.

Koen is a perceptive and very talented sound technician who is as concerned about the FOH sound as he is about making the band perform their best and feel comfortable on stage!

Koen is a pleasure to work with. He adapts quickly to the different PA's and venues to get the best sound possible. He stays very focused, paying attention to the details, the stage sound, looking out for the musicians, and tailoring his mix for each performance. He has a strong ear for all instruments which gives him a real edge behind the desk.

Koen is an honest, thorough and efficient sound tech. I was always confident that we had the best sound possible for each venue! After a few shows, when everyone had broken the ice, we sat down and discussed the expression and the ideal sound of the band and Koen would tell you everything straight, which is rare in the music industry. We discussed each of our individual sounds and he would say how he heard it and what his vision was and together we would try to make the best live sound possible. That’s what I like best about Koen, his honesty and enthusiasm.

Koen is a master of his craft when it comes to live sound. Not having worked with him before, he easily became one of our favourite mixers for live sound. Any challenges that were thrown his way were easily overcome with calmness and confidence, which is great for a touring band. It's always a pleasure hearing compliments from the crowd after the show on how the band sounded great and those compliments are definitely thanks to the great job Koen does. A highly recommend engineer and we look forward to working with him for years to come.

Koen is the kind of soundguy that you can count on will allways put in the effort and knowledge to make every gig as good as possible despite the situation.. and we've had some strange ones together! I would recommend him to anyone. He is also a nice dude to hang around with. Not to mention his beautiful ginger hair. It's like a lucious fire waterfall of orange juice. Tasty

Koen is an amazing sound engineer. He helped us make the best out of every stage every night. Went way beyond his duties to make us feel comfortable and is an expert with his equipment. Our tour wouldn't have been the same without him. Highly recomended and can't wait to work with him again!
