HILL on SoundBetter

Hi, my name is Xavier Collado (Hill) and I have a deep passion for music. In the past 10 years I've been mixing, mastering and producing music from artists around the world.

I'm graduated from the London School of Sound and I worked as an intern at The Dairy Studios in Brixton. I was the assistant engineer on projects for Tom Misch and Florence and The Machine.

Now I'm operating as a house-in engineer at 'Hill House Studio', my credits include millions of reproductions on all the streaming platforms. I offer a wide variety of top-grade services like mixing, mastering, production, audio repair and Dolby Atmos mixing.

Feel free to contact me if you have any questions.
