Kim Rosen Mastering Engineer
Kim Rosen Grammy Awards


Kim Rosen is a GRAMMY® nominated mastering engineer who works out of her own “Knack Mastering” located in Ringwood, NJ, USA.

Kim grew up in the western Massachusetts town of Northampton. Realizing early-on that music was a driving force in her life, Kim poured herself into the local music scene while searching out a way to carve a path for herself. In the summer of 2002 a friend turned her on to a mastering studio in NJ that was looking for an intern. Kim jumped at the opportunity, moved to NJ and began her journey at the age of twenty one.

After a couple of years in production, training and assisting in sessions, Kim was given the opportunity to take on her own mastering projects. Over the next five years, Kim would rack up hundreds of mastering credits including notable projects from Jeremy Enigk, Franz Ferdinand and Dashboard Confessional.

In 2009 Kim decided to go out on her own. She built her new studio with the help of renowned acoustician Chris Pelonis. The mastering room at Knack is a world-class listening environment, with analog and digital gear carefully chosen for its sound quality as well as its versatility.

Kim now has a growing client list that includes producers and engineers such as Ryan Freeland, Ed Cherney, Joe Henry, Matt Ross-Spang, Paul Q. Kolderie and independent and major label artists from around the world.

Kim’s mastered six Grammy® nominated albums. One winning in the Best Folk Album category as well as two nominations in the Best Engineered Album/Non-Classical category:

She was fortunate enough to master the remake of the Johnny Cash album “Bitter Tears” for Sony Masterworks which features artists such as Emmylou Harris, Steve Earl, Kris Kristofferson, Gillian Welch and The Milk Carton Kids as well as the beautiful Rhiannon Giddens and Iron & Wine rendition of “Forever Young” for the final episode of NBC’s television series “Parenthood”.

Kim continues to build a client base of artists, producers, labels and engineers who trust her ears, her experience and, above all, her respect for their mixes.
