Senior Mixing Engineer

"Mastering is the final - and one of the most critical steps in taking a record across the finish line. A good mastering studio can not only correct for any anomalies/shortcomings in the mixing environment, but a great Mastering Engineer can help eek out the last drop of emotion in composition, or a performance! Anything worth doing is worth doing well - and if your music deserves to be heard, it should be heard in the very best presentation possible, which definitely includes being Mastered."

Peter Doell, Senior Mastering Engineer
