My name is Oscar and I’m a sound engineer and music producer. I was born in Madrid, Spain, longer ago than I would like to admit and I live in London, UK since 2009, where I have my own studio space. I started in this music thing quite young and I worked many roles that allowed me to learn from different perspectives. 

As an artist I compose under different aliases being Ojah my personal solo project, having released in labels like SonyBmg, Universal, Partial Records, Zamzam Sounds, Steppas Records, Dubkraft, 18th floor, Dubforce, Digibeatmusic, Breakdrum Recordings, Alchemy Dubs, Dub Vibrations & El Manicomio and having done remixes for many artists and bands.

I started my own label Alchemy Dubs with the help of some friends back in 2008 and relaunched it in vinyl only form in 2015.

I occasionally play live as Ojah, doing live sets of exclusively own productions and dubplates, having played in different countries and festivals like Glastonbury, Vina Rock.... Japan.

Over the last few years my work has focused mainly on mastering (Alchemy Dubs Studio). I work with different companies and labels from indie to major and also directly with the artists.
