After signing to Moonwalk shortly after Kaks takti ette, Nurmsalu and Lõhmus decided that she would continue performing with Urban Symphony instead of pursuing a solo career.
In December 2008, Urban Symphony was revealed to be taking part in the debut edition of Eesti Laul, the newly created program to select the Estonian representative in the Eurovision Song Contest.
Their entry in the competition, "Rändajad", also served as their debut single as a group and was released on 5 January 2009; the song was written and produced by Lõhmus.
Urban Symphony competed in the final of Eesti Laul 2009 on 7 March 2009, where they were ranked first by the professional jury and second by the Estonian public.
As one of the top two total vote-getters, they advanced to the superfinal with Traffic.
In the superfinal, Urban Symphony and "Rändajad" received over 82% of the votes cast, winning the competition and holding the record for the biggest win margin in Eesti Laul history.

As the winners of Eesti Laul, Urban Symphony received the right to represent Estonia in the Eurovision Song Contest 2009 in Moscow, with "Rändajad".
They competed in the second semi-final on 14 May 2009, placing third and qualifying to the final; this was the first time Estonia had qualified to the finals since the introduction of the semi-finals in 2004, and remains their best placement in the semi-finals of all-time.
They later performed in the finals on 16 May, where they placed sixth with 129 points; this was the best result for Estonia since their third place finish at the Eurovision Song Contest 2002, and continues to be their best result since then as of 2020.

After Eurovision, "Rändajad" became a successful single internationally; it reached the top ten in Estonia, Finland, and Greece, the top twenty in Sweden, and also charted in Belgium, Switzerland, and the United Kingdom.
Later that year, Nurmsalu was invited to perform as a special guest during season three of Eesti otsib superstaari, the Estonian version of Idols, performing "Rändajad" with eventual winner Ott Lepland during celebrity duets week; Lepland would later go on to represent Estonia in the Eurovision Song Contest 2012, placing sixth in the final as well.
Urban Symphony released two other singles in their career, "Päikese poole" and "Skorpion"; both of which peaked in the top ten in Estonia.

In 2010, Urban Symphony announced that they would be disbanding.
The announcement was due to Nurmsalu wishing to prioritize motherhood, while the group's other members wished to continue their studies and pursue other interests.
