In person and vision

Da Goose Mastering is driven by Jeffrey de Gans (Gans is dutch for Goose). Jeffrey was born in 1971 and was obsessed with music, sound and technique from the day he was born. At the age of 10 he started messing with tapedecks, mixers and turntables while playing his sisters disco records. Later he had his own (illegal) radio-station, worked for a drive-in-show, worked for several radio-stations, produced and released over 80 vinyl-records, owned various record-labels and played worldwide on countless parties as a DJ.

One of his passions is making espresso; always fine-tuning the machines to make the perfect shot. This is something which can be found back in his mastering skills; always looking for the best and even push it just a bit more.

Da Goose Mastering (Da Goose Music) was founded as a music-production company in 1996. Jeffrey’s first real mastering-job dates back to 25 years ago and he has previously been nominated as one of the 4 best mastering-engineers from the Netherlands. Needless to say that he has a lot of experience, a great set of ears and serious knowledge of what he is doing.

Mastering is a craft, a science and some people even call it an art-form. It’s an obsessive look at the details, without losing focus of the big picture. It’s an objective opinion, It’s about quality, presentation, and translation, and most of all, it’s about your music, and doing everything I can to help realize your vision.”
