Swiss pop recording artist Patrick Nuo began his career in 2003, when he signed with Warner Music and released his debut album Welcome (2003).

[1] The same year, Nuo joined Zeichen der Zeit, a Christian music project whose first single "Du bist nicht allein" became a top ten success in Germany.

It produced the single "Undone", which served as the theme song for American comedy film Scooby-Doo 2: Monsters Unleashed (2004) in German-speaking Europe.

While not as commercially successful as Welcome in Germany, it would eventually become his highest-charting to date, reaching number four on the Swiss Albums Chart.

[1][3] In 2006, Nuo reteamed with Zeichen der Zeit to produce their second album Generation David (2006), and participated in another non-profit-making aid project when she provided vocals for the Fury in the Slaughterhouse cover, charity single "Won't Forget These Days," released during the 2006 FIFA World Cup.
