Coast Mastering is the premier audio mastering facility in Northern California. We are located in the historic Fantasy Studios complex at 2600 Tenth Street Suite 101C in Berkeley.

We have great news! We are very excited to announce that Michael Romanowski Mastering has grown. On October 1st, 2015 we became Coast Mastering. Check back here for news updates. We will have the new Coast Mastering site up and running shortly with announcements about events and pictures of the new facility! We will also be in touch with our current clients about contact information changes.

We pride ourselves on our studio spaces and our meticulous attention to quality and detail. Quality control of the technical specifications of the master is incredibly important, and we try to reflect that in our listening environment. We work out of the historic Fantasy Records building and take care to preserve its heritage while providing the benefits of modern techniques.

Our mission is to ensure the best possible quality and translatability of the music for every artist we work with. Mastering is the final stage of a project, and we believe that your project deserves not only the best ears to listen to it but also the best room and best equipment to execute the master.
