Klaus Derendorf, also known as "Klaus D," is a Los Angeles–based record producer and songwriter with millions of worldwide record sales to his credit including several Number 1 records on the Billboard charts and around the world.
Klaus is of German descent but was raised in several different countries due to his family living and working abroad. Klaus is fluent in English, Spanish and German, and credits his musical diversity to different influences from the US, Europe and Latin America. He picked up the guitar at age 9 and began playing and writing songs in junior high school bands from age 13, eventually settling in Los Angeles.
After finishing high school, Klaus started working with producer Rick Parashar in Seattle, Washington recording rock bands in the 1990s. He spent most of the 90s as a guitarist and songwriter in Los Angeles recording as well as touring with a variety of artists before focusing exclusively on producing and songwriting. Klaus credits 15 time Grammy winning producer David Foster and A&R executive Jaymes Foster for giving him his first production jobs at the Warner Music Group.
Klaus was elected to the board of governors of the L.A. Chapter of NARAS (National Academy of Recording Arts & Sciences), and is actively involved in all current industry issues as well as the election process of The Grammys.
Other notable producing and writing credits include Josh Groban's 'Closer', another Number 1 debut and over 7 million records sold, Australia's Stephanie McIntosh's 'Tightrope', Eden's Crush's 'Popstars' (feat. Nicole Scherzinger) and many others.
Recently he has been writing and producing records with Oprah Winfrey and David Foster protégé Charice, The X Factor (UK) judge Cheryl Cole of UK act Girls Aloud, Latin stars Anahi and Christopher Uckermann, formerly of RBD, and several other artists.
Cheryl Cole's track "Didn't I", produced by Klaus, and co-written with Cole and Andrea Remanda was released as the B-Side to Cheryl's solo debut single "Fight for this Love" and debuted at Number 1 in UK and Ireland in October 2009 selling just under 300.000 copies in its first week.
