The dance song was written by Dimitris Kontopoulos with lyrics by Viki Gerothodorou for her third studio album of the same name and was released on 9 December 2009 to radio stations in Greece and Cyprus by Minos EMI.

She performed as the opening act at his Sakis on the Waves beach concert[2] and the two eventually recorded a duet together, also written by Dimitris Kontopoulos, with MAD TV adding that the song's theme would provoke reaction.

[8] The track was recorded sometime in late November at Kontopoulos' studio,[9] coinciding with the artists' busy rehearsal schedule for The S Club.

[6] "Tharros I Alitheia" is a dance song[10] with heavy influences from varying electronic genres, including house and ambient.

The song begins with Tamta faintly singing the chorus, proceeding into the traditional verse-chorus format, with Rouvas performing the verse.

[4] The song premiered on Greek and Cypriot radio stations on 9 December 2009,[10] making it the third single from her third studio album following "S'Opion Aresei" (Dansonra) with Stereo Mike and "Kita Me".

[11] The concept of the video plays on a yin yang-type theme, with the light and darkness, innocence and eroticism continuously altering, thus contrasting with the song's title.

[7]Based on the concept, for the majority Rouvas represents the dark and erotic side of the video, while Tamta the light and innocence.

As the first verse begins, the shadowy figure is revealed to be Rouvas, with sweat dripping heavily down his face and an unidentified female hand touching him.

A new scene is added with Tamta standing in front of a white background with the wind blowing, wearing various loose, flowy costumes, one of which is a Laskaris Haute Couture creation.

"[11] The network concluded that "Impressive costumes, beautiful direction and two talented artists giving their best selves are the components of a successful music video."

[15] Tamta premiered the song at The S Club concert series where she served as a supporting act for Rouvas, using the track as her opening number.

As Tamta's part begins a video in the background is played featuring geometric shapes rapidly changing colours.

Tamta, wearing a purple leotard, proceeds to stand during the second chorus and four female backing dancers appear and perform a choreography.
