In 2002 he moved to the Netherlands to complete the American jazz program at the Prince Clauss Conservatorium in Groningen, under the mentorship of drummers Ralph Peterson and Owen Hart.
The folk-jazz band "Rakia", formed by Dimitar Liolev in Groningen, gave Borislav the opportunity to experiment with the integration of Bulgarian folk rhythms into jazz and vice versa. Eventually, this led him to his first attempts to compose original music for his own group – "Jazzanitza".
In 2008 Borislav completed a research on Bulgarian folk rhythms and drumming styles: ‘Long And Short Beats:The Mystery of Bulgarian Rhythms’. The study focuses on the essence of Bulgarian irregular meters and the historical development of folk drumming. It also includes ideas and concepts for expanding Bulgarian rhythms and integrating them into other styles of improvised and composed music.
