Ell and Nikki

National final constellation

Gasimov and Jamal separately took part in the Azerbaijani national selection, Milli Seçim Turu 2011. They qualified from the semi-finals along with three other artists to the final on 11 February 2011, where they won the right to represent Azerbaijan at the Eurovision Song Contest 2011 in Düsseldorf, Germany in May 2011. Although it was originally planned to send an individual as Azerbaijan, when the winner was announced, İTV had decided that both Eldar and Nigar would be going to Germany as a duo.

Eurovision win

In the 2011 Eurovision song contest Eldar Gasimov and Nigar Jamal performed together under the duo name Ell & Nikki. As the contest was taking place in a Western European country, the name change was made to prevent confusion of Jamal's first name being interpreted as a racial slur. Their entry, named "Running Scared", was written by Stefan Örn and Sandra Bjurman from Sweden and Iain Farquharson from the UK. The duo were aided significantly by the four Swedish backing singers, including Jessica Marberger and Vera Prada who had earlier in the year attempted to represent Sweden as part of Shirley's Angels.

They were the overall winners of the Eurovision final on 14 May which meant that Azerbaijan has the right to host the Eurovision Song Contest 2012.

2011–present: After Eurovision

Since winning the Eurovision final 2011, Jamal and Gasimov travelled to many European countries to perform their winning entry in the contest. The singers also received "Peace and Friendship Award" in Zonguldak’s Ereğli district for carrying a Turkish flag onstage during final scene. Azerbaijan and Germany have issued a postage stamp dedicated to Azerbaijan’s victory with Gasimov and Jamal at Eurovision.

In 2011, Ell and Nikki became the official faces of Nar Mobile, one of Azerbaijan's mobile communication providers.

When asked about planning to continue to work together in an interview to Daily Mail, Nigar Jamal said that the duo are planning to pursue a solo career at the moment, but did not rule out the possibility of more joint projects with Eldar Gasimov in the future.

In 2013, the duo recorded their second song named Music's Still Alive. The song was written as a tribute to Michael Jackson and released on 29 August 2013, the late singer's birthday. Both Gasimov and Jamal describe themselves as Jackson fans.
