She has been singing and playing folk lutes from her childhood, performing music from Greece and the Balkans. Later she developed an interest in contemporary music, blending elements of folk music with contemporary harmony and improvisation. Her critically acclaimed debut album "The Garden of Rila" established her as a first class folk musician and singer of the new generation, as well as an accomplished composer and orchestrator. Martha's extraordinary voice
combines the Greek and Middle Eastern ornaments and microtonal subtleties, with the rich colors of Balkan singing. Her dazzling technique on the lafta and the saz, is often compared to the skills of master musicians of both folk and jazz origin. In March 2013 she featured in the cover of fRoots magazine as "Balkan music's rising star". With the Martha Mavroidi Trio she has toured in Sweden, Spain, France, Germany, Austria, Turkey, Cyprus and Greece, and have performed at Womex Globalkan Scene in 2012. She has composed music for prize-winning short and feature films, and for dance and theater productions, and she has released three albums: The Garden of Rila (2009), Portaki (2012) and Agiorgitiko (2014).
