    LU worked his magic again!🙌🏽 His approach to mastering isn’t just about making things “louder”, but he makes sure to bring out the best qualities of the track, whether it’s making the vocals sound more crisp, or adding more punch/warmth to the low end, you won’t be disappointed!

    This is my third time working with Lu and he is INCREDIBLE at what he does. His expertise is truly professional. Your music will be radio ready coming from him, no matter your actual sound or style. His turnaround is great. At this point he's my go to for all mastering work!

    Lu is simply one of the best engineers in my book period. He pays attention to what his clients wants and he goes over and beyond to achieve his clients goals. I would recommend him to anyone.

    Thankful to work alongside Luis @ MidSideSound. Even though I'm a mix engineer as well, I still hire Lu & he knocks it out of the park every time. Having an engineer that can turn your ideas into much more is a key essential especially when you have a client roster jumping from Dreamville all the way to a punk rock band in Delaware. Lu has mastered 4 projects I’ve brought to him and together we have worked on over 28 singles from start to end. Go to Lu if you want your vision brought to life.
