    Jonas did an incredible job on the master of my new song! He gave detailed information on my original mix which optimized the dynamic range and clarity of the finished song. He responded quickly, was professional, and I couldn't be more pleased with the quality of his work. I will definitely be working with him again in the future!

    Jonas brings out the very best elements of your track. He has a great combination of talent, skillset and creativity when it comes to production and mixing. Looking forward to working with him again, and would highly recommend him for anyone who wants to create or bring out the best of their craft.

    Jonas is the absolute best. Jonas took a track I had been touring with for a little while, and he completely re-imagined the mix to a whole other level. He's patient, professional, and insanely talented! He is truly the best and I highly recommend!!!!

    Jonas is my only choice ! My project was completed on time and with the upmost detail and precision. His creative input also helped me to push my project further than I ever imagined. His skill set and ability across many genres are priceless. Adding to his talent as a producer with further skills of the best mix and mastering l have found. I will only use Jonas moving forward for all my music needs.

    Jonas has also mastered "Look At Who I Am (BLKZEN Remix)" for me. Check out the song if you wanted to hear his work and quality!

    Jonas is the most skilled/talented/humble/hardest working/nicest guy I have ever met. He has mixed/mastered my original song "Look At Who I Am (Feat. Lu Alex) and I am going to ask him to be a part of my team and mix/master all my future songs for me. I do NOT want many people to know him because I want to keep him on my side.. lol Not going to lie he is absolutely 100 stars!

    Jonas, the most kindest and unbelievable talented producer/songwriter! Jonas has written and produced songs to a pop artist that I manage. His unique, distinctive style really makes the records he creates stand out. His skills in mixing are outstanding, not to mention vocal editing! Always such a pleasure to work with him. A true gem :)
