Mastering Engineers

Billy Klein graduated with honors as a Recording Arts major from Loyola Marymount University in Los Angeles, CA. After starting his career at a major label A&R department he transitioned into the studio and worked daily with a talented roster of artists, engineers, and producers. In 2013, Klein co-founded Hybrid Studios and his engineering focus shifted to Mastering. Over the last twelve years he has contributed to the recording, mixing and editing of talents like Shakira, Keith Urban, Adele, Matisyahu, Augustana, Leona Lewis, The Bravery, and Michael Grimm.
What is my mastering philosophy? My goal is always to create well-balanced and competitively loud mixes. I want to always improve every song that I receive. In today’s market of music streaming and loudness normalization, dynamics have become increasingly important, and I create masters with encoding and streaming in mind from the start. As far as balance, I want everything to sound just as great on your smart phone as it does in your car. The trick is creating masters that still have bass information on a smart phone, without making your ears bleed from bright cymbals or guitars, but also won’t sound muddy from too much bass when you listen in the car. I tend to dislike bright mixes and masters because today’s listening environment is lacking in playback systems capable of even playing back bass information.

Brian Frederick graduated from Long Beach City College with an Associates Degree in Audio Engineering.

Frederick worked his way up from intern to staff engineer, and honed his craft working with some of the biggest names in Pop and Hip Hop. He has contributed to the recording, mixing and editing of talents like Wiz Khalifa, DJ Mustard, Snoop Dogg, Kaskade, DJ Quik, and Isabella “Machine” Summers (Florence and the Machine).
What is my mastering philosophy? My approach is simple: serve the song and album, stay out of the way of the song as much as possible, and try to bring out the best aspects of the mix while minimizing the worst. An artist spends countless hours making the best version of the song(s) possible, and I really take that to heart. I’m not going to put my “stamp” on the song, per say. Every song is different, and every Mastering session is crafted according to what is brought to the table. The end goal is to create highly enjoyable Masters that sound incredible across all playback platforms. It should always sound the best it possibly can, from the phone to the club, to the backpack with speakers, to the Main Stage at the festival.
