Felix has become our go-to mastering engineer over the years. He has an amazing approach with musical and inspiring results. He always makes our tracks better and is just a lovely guy to work with!

Stuart Hawkes is hands down my favorite mastering engineer to work with. He has this rare ability to elevate every mix — bringing out that final bit of polish, without ever losing the essence of the track. There's always a touch of magic in what he does. It's subtle, but it makes all the difference.

I've been working with Hippy for the past 2 years on my band The Clause's music and artists I produce and write with. Every time I send Hippy a mix, I'm blown away by how he brings it to life and adds that perfect element of shine and polish to my tracks; he's a magician!

Working with Felix is always incredible! Not only is his work consistently amazing, but he is always incredibly accommodating, and he delivers with impressive speed. He approaches every track with care, professionalism, and a genuine passion for the music. On top of that, he is just a lovely person to work with - kind, communicative, and he always goes the extra mile. I can't recommend Felix more highly!

The revised master of Silent Ricochet is “Banging” We love that..!!. We compared Metropolis master to some other online mastering and it was like a Gold Standard in comparison.

We’ve worked with Metropolis on two albums now and we are always blown away by how the mixes are brought to life. Stuart and Metropolis are absolutely wicked and extremely sonically versatile…. also mad speakers!

These sound exactly how I hoped they would, please let Matt know how happy I am with them. Gripped especially hits in an entirely new way. Appreciate you communicating with me so well during the process.
