Born and raised in Melbourne Australia, to Greek parents.
Theodosia has been singing, acting, and dancing ever since she can remember.

All throughout her school education Theodosia starred in several theatrical productions and excelled in every class related to drama, music, and dancing.

After graduating from high sghool, the family moved to greece.

Theodosia was accepted to study at the National Theatre Academy of Thessaloniki where she completed her studies.

Simutaneously, she studied at the Aristotelian University of Thessaloniki obtaining a degree in Arts.

Music, being her first love she kept up with her musical studies and she sang and played every chance she got. This led Theodosia to start her music career with the group 'Μπλε' ( "BLUE" in greek).

The group's first album was called "ENOHES" ( "GUILT").

The album became gold and the 'Blecraze' had begun.

This album launched Theodosia's solo career and her new album titled "Ipoptos Cosmos" (Suspicious World) in 1999, where she participated in the composition and the lyrics with the band's musicians.

Theodosia explored the rock sound in ways that her live performances have always been considered an event.

In 2002 she comes out with a totally different sound experimenting on new vocals and a totally new approach in orchestration composition and lyrics.

The hit song 'Thalasa' is still one of the most frequently played songs on the air today.

In 2006 Theodosia's next album titled 'Leoforos tis eva's', (Eve,s avenue), is more of a confessional album that embraces yet again, a new approach in her sound.

She has co-composed and co-produced it and wrote the lyrics.

BaBallou was born in 2008 , as a result of Theodosia's relentless experimentation with new sounds . By successfully blending the Bouzouki into Rock , Theodosia has again broken the boundaries of conventional music.
