Our Team

Alexander Arrindell (Head Sound Engineer)

Hi, my name is Alexander Arrindell. I am a producer and audio engineer that goes by the name of "THATBOYSEVEN". I was born in England in 1998 and founded L7 Audio Engineering in February 2022. Although I was born in England, I spent most of my life on an island in the Caribbean called Sint Maarten. Within my teenage years on the island, I discovered my passion for music production and quickly began teaching myself how to produce music.

Once I graduated high school in Sint Maarten, I moved to the Netherlands in 2016 to pursue a higher education. Here, I studied Business and Management for 2 years at the Rotterdam University of Applied Sciences. However, since music has always been a big part of my life, it didn’t take long for me to realize that it's the only thing I wanted to do. I then decided to pursue studying Audio Production and Engineering at SAE Institute in Amsterdam in 2018. I really enjoyed my time there, and got to develop my skills as an overall producer. In my second year at SAE, I got the chance to experience working on a Solid State Logic 6000E console which sparked a whole new obsession with audio engineering and the sound of quality outboard equipment.

In September 2022, I did my thesis on Acoustics and completed my studies at SAE with a BSc (Hons) in Audio Production. During the course of my study, I freelanced in various studios as a recording engineer and got to work on many projects for local artists. Now that I have gained enough experience locally, I'm willing to use my expertise to also help artists globally!
