Cirse was founded in José Mármol[1] near Argentina's capital Buenos Aires in 2003 by vocalist Luciana Segovia and brothers Gabriel (Guitar) and Sebastián "Ziva" Leopardi (Bass).

The band covered the Luis Alberto Spinetta song "Alma De Diamante" which was featured on their debut album.

Listeners of radio station FM Rock & Pop voted Cirse as winner of Bombardeo del Demo so the group was allowed to share stage with national well-known band Catupecu Machu at Teatro Colegiales in Buenos Aires.

After a summer tour the band was asked to be opener for Paramore at their show in Buenos Aires at Luna Park on February 24, 2011.

In May and July 2011 the band toured the region Buenos Aires and South West of Argentina including shows in Lanús, Quilmes, Santa Fe and Ramos Mejía.

Short after that tour the band supported Avril Lavigne at Estadio Malvinas Argentinas in Mendoza on July 24, 2011.

[4] Two month later the band won a slot at 2011s edition of Pepsi Music Festival through a competition hosted via social network Facebook.

[11] The Leopardi brothers and Magliano went on to form a new group with singer Ana Devin, called "Ramen",[12] and Segovia chose to move into a solo career.
