Caleb Shreve began his professional music career at Sony Studios in New York in the early 2000's where he worked mostly as an assistant to mix engineer, Tony Maserati, and many other renowned mixers such as Michael Brauer and Bruce Swedien. At Sony, Caleb worked his way up to become a full-time engineer and joined the Sony Music Special Projects team, a position that allowed him to record albums for all of Sony's biggest artists including Jennifer Lopez, Ricky Martin, Jessica Simpson, and Michael Jackson. He was also afforded the opportunity to work closely with several songwriters and producers such as Rodney Jerkins, Walter Afanasieff, and Desmond Child.
In 2004, Caleb left Sony and went freelance as a regular engineer and mixer for Sean "Diddy" Combs, Mario Winans, and Nick Cannon as well as continuing to work with Jennifer Lopez and Marc Anthony. It was only a matter of time before Caleb would be met with the perfect opportunity to transition into full-time songwriting and music production, and that moment was soon realized in 2007 when he was tapped to produce two songs: "Be Mine" and "I Need Love" for the Jennifer Lopez album Brave.
While producing and mixing for major pop artists, Caleb also kept himself rooted in indie rock and soon discovered that his years of experience working on such high level projects brought technical skills to mixing and producing that set him apart from his peers. He quickly garnered the attention of such bands as Phantogram, Ra Ra Riot, and Stars. During this time he also wrote and produced the last Northern State album with Ad-Rock from the Beastie Boys. Shortly after he signed a publishing deal with BMG/Chrysalis through writer Billy Mann and has since written with artists such as Tegan and Sara, Ingrid Michaelson, Carly Rae Jepsen, and Santogold.
