Mastering is the final stage of a music track’s production before release or manufacturing, it is the last opportunity to release and extract the elements that the music was created to have. It brings out depth and substance and transforms the music in to a 3D element when done properly. Mastering is about creating this sound whether to be played on huge systems or little personal players. For me it is also about respecting and understanding the process involved to where the original tracks have come from and where the masters will end up. My focus is to prepare masters and vinyl cuts with Clarity, Dynamics & Depth.
