Jason Rowe was born in Yeovil, England, in December 1969. He moved to London in the mid-1990s and began working with producer Joel Bogen. A single, "Don't Give Me Away", was recorded under the name "Jai" and released on independent record label M&G Records in February 1997. The success of the single in the UK and across Europe attracted the attention of RCA Records, who released Rowe's debut album, Heaven, later that same year. The album featured mostly original works co-written by Rowe with Bogen, Christopher Bemand, and Rob Watson, as well as contemporary covers of the Arthur Hamilton standard "Cry Me a River" and J. J. Cale's "Magnolia". The single "I Believe" was a minor hit in the United States, and the album itself made a brief appearance at #49 on the Billboard Heatseekers Album Chart.
After residing for a couple of years in New York City, Rowe returned to Europe, eventually settling in Berlin. He continued to write and perform his own music, and also penned songs for the German hip hop band Die Fantastischen Vier. Signing with manager Jobst Henning-Neermann, Rowe briefly returned to the U.S. in 2006 to record a new solo album. Lovelife was released February 23, 2007 on German record label Four Music, but received only limited promotion and distribution. Shortly thereafter, Rowe contributed a song, "The Dreaming", to an advertising campaign for the Tommy Hilfiger fragrance of the same name.
Rowe has since moved back to England. In June 2011, he married American musician Daphna Dove, having met her several years earlier when she contributed backing vocals to Lovelife. Most recently, Rowe collaborated with Dove in forming two musical groups, The Strings and VictoriA.
