The song was performed by Elnur Hüseynov, who was internally selected by the Azerbaijani broadcaster İctimai Television (İTV) in March 2015 to represent the nation at the 2015 contest in Vienna, Austria.

Performing during the show in position 11, "Hour of the Wolf" was announced among the top 10 entries of the first semi-final and therefore qualified to compete in the final on 14 May.

Between 2011 and 2013, Azerbaijan organized a national final titled Milli Seçim Turu to select the performer, song or both for Eurovision.

In 2014, the broadcaster utilised an existing talent show format titled Böyük Səhnə where the winning performer would subsequently be given an internally selected song.

[3][4] On 15 March 2015, İTV announced that Elnur Hüseynov would represent Azerbaijan, performing the song "Hour of the Wolf".

In February 2015, Hüseynov won the Turkish version of the reality television singing competition The Voice: O Ses Türkiye.

[5] The selection of Elnur Hüseynov and "Hour of the Wolf" as the Azerbaijani Eurovision entry was based on the decision of a national jury panel, whose members included the General Director of İTV Jamil Guliyev and Head of Delegation Tamilla Shirinova, from three potential entries performed during an audition round on 13 March.

[6][7] "Hour of the Wolf" was written by Sandra Bjurman, Nicolas Rebscher, Nicklas Lif and Lina Hansson, and was presented alongside the entry announcement via the release of the official music video.

"[8] Elnur Hüseynov made several appearances across Europe to specifically promote "Hour of the Wolf" as the Azerbaijani Eurovision entry.

[14] On 18 April, Hüseynov performed during the Eurovision in Concert event which was held at the Melkweg venue in Amsterdam, Netherlands and hosted by Cornald Maas and Edsilia Rombley.

[15] On 24 April, Hüseynov performed during the Eurovision Pre-Party, which was held at the Place de Paris Korston Concert Hall in Moscow, Russia.

The staging for the performance focused on dark colours with the LED screens displaying a mystic atmosphere with an arid forest, a full moon and wild nature.

[30] At the end of the show, Azerbaijan was announced as having finished in the top ten and subsequently qualifying for the grand final.

The jury consisted of five music industry professionals who were citizens of the country they represent, with their names published before the contest to ensure transparency.

This jury was asked to judge each contestant based on: vocal capacity; the stage performance; the song's composition and originality; and the overall impression by the act.
