The band was founded in July 2007 by Howen and Joshua after they listened to Alejandra’s singing. The music was born heavily influenced by European Symphonic Metal bands, characterized by the inclusion of a female lyrical voice, and the use of orchestral arrangements.

In 2012 the band began to record what would be their first album: Dark Desires, which was released at the beginning of 2013. Their composition and melodies and its nuances captivated a large and heterogeneous public. Dark Desires obtained highly positive national and international reviews that were published in different specialized media. Germany, Japan, Colombia, Belgium, England, USA, France, Canada and Italy are some of the countries in which the album has garnered numerous accolades from the sales of a significant amount of records in those countries.

At the end of 2014 the band published its first music video from the title album, that currently has more than 260k views. Throughout 2015, the group participated in a national contest organized by Icarus Music, which resulted in the majority vote choosing Elessär, and thus becoming the only band supporting Epica at a sold out show in Teatro Flores, Buenos Aires.

In addition, that same year they obtained the 2nd place in a contest organized worldwide by Nuclear Blast who together with the band Nightwish were looking for the best version of the song “Elan” from their album “Endless forms most beautiful” (2015). Elessär was the only band from the American continent to enter the top performers.

Elessär spent the next years playing shows all around the country, and performing together with big acts such as Accept, Epica, Rata Blanca, among others. In 2017 under the direction of Andres Tolcachir, they played with Neuquen’s Symphonic Orchestra, being the first time that an event like this took place in Argentina.

Throughout 2017 and 2018 the band dedicated to the production of their latest independent album Kósmos, which was released on April 2019.
