"I call Sandy my magic dust. I could use all sorts of cliched phrases to describe what he does to tracks - elevates the work, adds that final sheen blah blah blah, but it's truly deeper than that. A man that fundamentally understands both music as storytelling and sound as science is a rare combination. My artists are always staggered when the masters of their songs come through - many of them young indie artists who come to understand what mastering actually IS for the first time through experiencing Sandy's work. I shall be working with him for the rest of my life whether he likes it or not."

"Sandy at Sonic Fusion is my go-to mastering engineer because he delivers high quality results in a timely fashion. He has a great ear and understands what each track needs in order to reach its full potential, plus he’ll provide feedback if there's something in the mix that is hindering the track. Best mastering service I’ve used, by far!"

"I've been using Sonic Fusion's services for mastering most of my label's releases since 2017, and in the 7 years since then, not a single artist I've supported or listener has been disappointed with the results; this includes both more dynamic home-listening music and dancefloor bangers. Working with Alexander is always professional and collaborative, with useful feedback being provided in the process. I highly recommend the service!"

"Sandy is a pleasure to work with, gives useful advice and is open to discussion to achieve the best result when it comes to mastering and ensuring our releases hit where they are supposed to."

"The fixer! Our track could not shine brighter with his help! From mixing to mastering, everybody could use some of his ears. The only person we trust in the electronic scene."

“Sandy came to the rescue on a mixdown for us recently. What he gave back to us was perfectly balanced, weighty and had the type of clarity that only someone with experienced ears can achieve 10/10”

"Sandy has been my go to mastering engineer for both personal, and Grey Meta projects, for many years. The combination of his ability to decipher and instill all the subjective audio adjectives into mastering projects, his patience, and his technical prowess make his masters unparalleled. I can say this because I've A/Bd them to death. Whether I want crushingly loud, some character added or just a very clean clinical master, Sandy is the man, with the plan, monitors, room, and ears."

"Sandy Finlayson is organised and quick to respond. He is dedicated to his work and always delivers a result that exceeds expectations. He has been so dedicated to making my album the best it can be, I am so very grateful. He is also very patient and goes out of his way to help, which makes all the difference. I would have no hesitation in recommending his audio engineering work. His own music exemplifies his talent as an innovator and musical wizard. His latest album "See it Through" is a true masterpiece I just can't stop listening to!"

"I've been getting my tunes mastered by Sandy for years. From the feedback to the quality of the masters there's no one I'd rather go through to put the finishing sparkle on my work. With his help my mixdowns have gone from okay to good to great and his notes have pushed me to get better at my craft. 10/10"

"Sandy has helped me out finishing off my mixes and mastering my music countless times over the years and I've always been happy with the results. Most importantly he is a delight to work with and is happy to take on feedback and ideas. Would absolutely recommend him to anyone looking to take their music to the next level, this guy knows his stuff!"
