Svetoslav Costoff is born in a family of musicians in Sofia. His grandmother, Lilia Costoff, is the first bulgarian violinist, which has performed in one evening „the three B” (concerts for solo violin by Bach, Beethoven and Brahms) with the Sofia philharmonic orchestra. His father has played the cello in several famous orchestras in Europe and has performed also as a soloist. Growing and thriving in the embrace of music, Svetoslav Costoff goes already four years old in his father’s footsteps and begins to play the cello. Later he chooses his instrument to be the guitar. His first teacher Emil Petrov inspires his musical development until starting his bachelor studies. After an outstanding graduation of the Academy of Music in Sofia under the leadership of his main teacher – Rossen Balkanski- he expanded his education at the Academy of Music in Berlin with the famous pupil of Karl Scheidt – Prof. Eugenia Kanthou. Master classes with Gerhard Reichenbach, Alvaro Pierri, Zoran Dukic, József Eötvös and others strongly influenced his musical development as a guitarist and interpreter. But Svetoslav Costoff points as a crown of his musical education the regular visiting of rehearsals of the Berlin Philharmonic Orchestra, at the time he was still a student in Berlin, with the scores of the current played works. During and after his studies he became laureate of several international competitions for guitar in Europe. After that starts his active concert career. At first he performs mainly for the Live Music Now-Foundation von Yehudi Menuhin in Berlin, where he is the first accepted solo-guitarist. He gives active concerts for five years for the foundation in Berlin and Brandenburg. Since 2011 works Svetoslav Costoff as a freelance artist in Berlin- there he resides with his wife and his son until today.
