About

From Spain to Los Angeles.

A full-tuition SGAE scholarship brought Guillermo from Spain to Berklee College of Music, where he graduated in Music Production and Engineering in 2012. Based in Los Angeles since then, he works where music and picture meet.
He approaches every project as a musician. On a record, that means preserving the performance while giving the production shape and impact. In picture work, it means helping the story land through sound. The finished mix then has to translate cleanly in the format it was built for, from stereo to surround and Dolby Atmos.
