John Greenham has always been passionate about music. Originally from the south of England, he began playing music at thirteen when he found a guitar in the laundry room. John was inspired to move to California for its music and culture. He played both guitar and bass in San Francisco bands, and ultimately discovered that he preferred being on the other side of the glass in the recording studio. In 2006, he moved to Area 51 Mastering and worked alongside Stephen Jarvis, where he won two Grammys for his work with Los Tigres del Norte. After that, John briefly worked at The Annex in Menlo Park, and then concluded his work in San Francisco in the Coast Recorders building on Mission St., where he won another Grammy for his work with Los Tigres del Norte.
