Welcome to Horizontal Studios – Based in the peaceful surroundings of Collserola National Park, just outside Barcelona. The studio is built 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.

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