Born on 7 April 1967, the Hamburg-based DJ/producer did his first musical production in a porno synchronization studio. This very first single unfortunately flopped. 4 years later he produced his first chartbreaker : Ritmo de la Noche with the project Chocolate (sung by Verona Feldbusch). In August 1990 the single, released Europe-wide, reached #23 in Germany and remained in the charts during 21 weeks. The same year, Alex Christensen produced a remix of the song Oliver Cheatham's Get down Saturday Night.
He got his first taste of fame in 1991 with his project U96 when he spearheaded that group's powerful techno single Das Boot, a remix of the theme-song from the German movie of the same name. This track became an instant smash in Germany and other parts of Europe. A string of albums and singles were released by U96 over the following decade, with hits like I Wanna Be A Kennedy and Club Bizarre.
In 1994 Alex's former girlfriend was running Warner Chappell, which looked after Frank Peterson's administrative company Petersongs. She knew that Alex was not happy with the people he was working with at the time and so she organised a meeting between the two producers. 3 weeks after his initial introduction to Frank, Christensen was offered the Marky Mark project and so Frank and Alex's partnership began with the album Life In The Streets. Alex's administration company was originally called Pink as reflected in that album's credits, but was later changed to AC Music. Alex Christensen does not play any instrument but, as he himself says, "I learned through the years how to love and cherish computers".
In the same year Frank and Alex also formed the group PeCh featuring Chris Thompson, which released not only its branded singles but also under this name the duo provided various remixes for other artists. Peterson later invited Alex to co-produce tracks found on Sarah Brightman's Fly and Question Of Honour, and Princessa's Calling You.
In 1995, Alex Christensen produced the single Baby I Need Your Lovin, under the name of Wave Kid. Featuring a solo male vocalist, the style was between Inside Your Dreams and Club Bizarre.
As producer and composer he also worked for Tom Jones, N'Sync (If Love Is Blind), Oli.P and Marianne Rosenberg. He also did remixes for Jean Michel Jarre.
In 1997 he started his collaboration with Tony Catania and the group R'n'G (Urban/Motor). Together they released the singles Rhythm of My Heart (#35 in the charts, 12 weeks of presence), Here Comes The Sun, (#21, 23 weeks of presence). The next year came the succesful single Open Up Your Mind (#14, 13 weeks of presence), followed by the top 30 single Can't You C, I Love Your Smile (#47), Darlin' I Think About You (#73) and Tequila (#97).
Frank Peterson and Alex also worked on the Bravo All Stars single Let The Music Heal Your Soul which was written by Alex. At the end of 1998 he also produced Rap Allstars single Last Christmas (a remake of George Michael's song).
In 1998 too Alex created his own label Kingsize as well as the euro-pop project Rollergirl. Many hits followed : Dear Jessie (#13) then Luv You More in November 1999, then the album And The Party Keeps On Rollin and the single Eternal Flame.
