Since 2006 Deep Zone's songs have featured the vocal talents of Joanna Dragneva, who was born in Sofia in 1987. From an early age Joanna discovered that she was born for music and television.

In 2007, the Depp Zone Project  released their single " DJ, Take Me Away", a collaboration with DJ Balthazar. The song has reached #2 in MTV Europe’s World Chart Express and due to its massive successful was always the favourite to respresent Bulgaria in this year's Eurovision Song Contest.

He has performed at every major club in his country as well as on many big raves and various radio and TV shows.

Since 2003 he has been producing music with his studio partner JackRock and they have so far released more than fifty tracks and remixes on different labels. Balthazar's own style varies between groovy/minimal techno and electro/tribal/progressive house, always corresponding with the newest records on the scene. Usually his sets are quite energetic and technically perfect.

Bulgaria's entry is one of the boomakers favourites to qualify from the second semi-final and to finish in the Top 10 in the final, however fan polls have beeen rather less promising, yielding a mixed bag of results.
