Andreas Carlsson (born 3 April 1973) is a Swedish music producer, composer, and pop songwriter.

Carlsson was part of the Cheiron Studios team until the studio was closed down in 2000.

In January 2001, former Cheiron-members Andreas Carlsson, Kristian Lundin and Jake Schulze assumed the lease of the legendary Cheiron studios. Two years later, they launched production-company The Location and publishing-company Location Songs, where writer Savan Kotecha is signed.

In 2008 Andreas Carlsson formed production/publishing company Meriola with fellow producer, composer and songwriter Anders Bagge, who has written and produced songs for Madonna, Janet Jackson and Jennifer Lopez among others.

In 2009, Carlsson wrote his autobiography "Live to win - låtarna som skrev mitt liv" (The songs which wrote my life), about his career and journey to where he is today.

Carlsson frequently collaborates with writers Desmond Child and Chris Braide. Together they have written many recent American hit songs, including "Invisible" for the American Idol contestant Clay Aiken. The song became one of the most performed on American radio in 2004. A more recent collaboration is Katy Perry's "Waking Up In Vegas", featured on her album "One of the Boys". Andreas also made the song Strange, Alice in Wonderland's soundtrack, which was performed by Tokio Hotel and Kerli Kõiv.

William Bradford "Bill" Champlin (born May 21, 1947, Oakland, California) is an American singer, guitarist, keyboard player, arranger, producer, and songwriter. His performance work is principally associated with the bands Chicago and the Sons of Champlin. He has won multiple Grammy Awards for songwriting.

As a child, Champlin demonstrated a talent for piano, and eventually picked up the guitar after being inspired by Elvis Presley. He started a band, The Opposite Six, while at Tamalpais High School, in Mill Valley, California and went on to study music in college, but was encouraged by a professor to drop out of school and pursue music professionally.

The Opposite Six, Champlin's band from high school, changed their name to the Sons of Champlin, and eventually recorded a number of well-reviewed but poorly-selling albums (including Loosen Up Naturally and Circle Filled With Love) by 1977, when the 30 year old Champlin moved to Los Angeles.

In LA he began extensive studio session work. He was especially in demand for his singing, appearing on hundreds of recordings throughout the 1970s and 1980s. The National Association of Recording Arts and Sciences (NARAS) awarded Champlin the Most Valuable Player peer award for male background vocalists in 1980.

Michael Joseph Jackson (August 29, 1958 – June 25, 2009) was an American recording artist, entertainer, and businessman. Often referred to as the King of Pop, or by his initials MJ, Jackson is recognized as the most successful entertainer of all time by Guinness World Records. His contribution to music, dance, and fashion, along with a much-publicized personal life, made him a global figure in popular culture for over four decades. The seventh child of the Jackson family, he debuted on the professional music scene along with his brothers as a member of The Jackson 5 in 1964, and began his solo career in 1971.

In the early 1980s, Jackson became a dominant figure in popular music. The music videos for his songs, including those of "Beat It", "Billie Jean", and "Thriller", were credited with transforming the medium into an art form and a promotional tool, and the popularity of these videos helped to bring the relatively new television channel MTV to fame. Videos such as "Black or White" and "Scream" made him a staple on MTV in the 1990s. Through stage performances and music videos, Jackson popularized a number of complicated dance techniques, such as the robot and the moonwalk, to which he gave the name. His distinctive musical sound and vocal style influenced numerous hip hop, post-disco, contemporary R&B, pop and rock artists.
