Welcome to Horizontal Studios – Based in the peaceful surroundings of Collserola National Park, just outside Barcelona. We’ve built our studio from the ground up, acoustically tuned for accuracy and balance, so that every detail in your song translates clearly.

At the heart of the studio is Matthew Styles-Harris, a multi-platinum certified engineer with well over one billion streams to his name. Trusted by both underground artists and global pop acts., whether it's a raw track or a major label release, Matthew brings the same focus, taste, and experience to every project.

He works with a handpicked selection of high-end analogue gear from Maselec, Knif, Neve, Terry Audio, and Thermionic Culture—paired with Prism Sound converters and world-class monitoring from Grace Design, Amphion, Genelec, and Dutch & Dutch. It's all about creating the right conditions for great sound, and knowing how to use the tools with intention.

The studio upgraded with a certified Dolby Atmos 7.1.4 setup—bringing spatial mixing into the fold and opening up new creative possibilities for immersive audio projects.

Feel free to explore some of the music we’ve worked on below. Each project is a reflection of the close collaboration we build with our clients. If you're ready to take your music to the next level, get in touch—we’d love to hear what you’re working on here
