After her departure from Glashaus and a label change to Universal Urban Records in 2007, she released her second album Darum leben wir in February 2009. A gold-certified the top ten success, it spawned three singles, including "Stadt," the fourth biggest-selling single of 2009 in Germany. In 2010, she won the ECHO Award for Best National Artist Rock/Pop.Also in 2009, Steen voiced the character Tiana in the German dub of Disney's 49th animated feature The Princess and the Frog.

Impressed by her voice, Steen was invited to contribute backing vocals to the trio's 1997 debut album Quadratur des Kreises, gaining her first official feature credit on their collaboration "Telefonterror." The following year she appeared in Freundeskreis' music video for their single "Wenn der Vorhang fällt" and accompanied the band on their first tour throughout German-speaking Europe. Further collaborations with Freundeskreis failed to materialize as Steen decided to move to Hamburg in hopes of a solo career launch and soon she was offered a contract with the independent label Booya Records. Due to musical differences she soon asked for a release however. Steen holds both German and American citizenship.Breakthrough with GlashausIn 2000, 3p label head Moses Pelham took notice of Steen after listening to her demo tape. Following a first meeting in February 2000, the pair began recording "So Lange," a song that appeared on the 3p compilation album Evolution. Steen eventually signed a solo contract with the Frankfurt am Main-based soul label and started work on what initially was to be her solo album but soon moved into a collaborative endeavor and finally emerged as the debut album of Glashaus, a trio consisting of Steen, Pelham and 3p studio musician Martin Haas, with Steen contributing the lead vocals. After months of recording the group released their debut single, the piano ballad "Wenn Das Liebe Ist," in 2001. The song became an instant success, reaching number five on the German Singles Chart, and garnered the band three ECHO Award nominations. Four albums later, the band unofficially disbanded in 2006. Steen decided not reunite with Pelham and Hass for another album and in 2009, she was replaced with a new female leading singer.Solo careerAmong three successful albums and a number of hit singles the trio also partially produced Cassandra's solo album, Seele Mit Herz, which was eventually released in summer 2003 and yielded the slow jam "Wenn Du Lachst" as its lead single. Both the album and the single were a critical success but widely failed to chart or sell noticeably on the German Media Control charts. Additionally, Steen continued singing background and chorus for label mates Illmatic, Franziska and Setlur, and made guest appearances on several new releases by J-Luv, W4C, Melbeatz, Bushido and Curse. Her collaboration with rapper Azad, "Eines Tages" was released in 2006.In February 2009, Steen released her second studio Darum leben wir on the Universal Domestic/Urban label. Containing production by Marek Pompetzki & Paul NZA, Andreas Herbig und Michael Herberger, the album reached the top ten of the German Albums Chart and sold more than 100,000 copies domestically, resulting into a gold certification by the IFPI. The album's same-titled lead single reached number six on the German Singles Chart and was chosen to represent Baden-Württemberg on the 5th Bundesvision Song Contest where Steen finished fourth with 103 points. Second single "Stadt," a collaboration with Ich + Ich singer Adel Tawil, was released to even greater success, reaching number two in Germany and the top five in Austria. It eventually became the fourth biggest-selling single of 2009 in Germany. Also in 2009, Steen voiced the character Tiana in the German dub of Disney's 49th animated feature The Princess and the Frog. "Never Knew I Needed," a duet with original singer Ne-Yo, was the first single to be lifted from the accompanying soundtrack. In 2010, she won the ECHO Award for Best National Artist Rock/Pop.
