Jazzanitza translates asymmetric rhythms - a distinctive feature of Bulgarian folklore - into the language of contemporary jazz, following the well-trodden paths in the musical heritage of folk improvisers such as Ivo Papazov, Petar Ralchev, Teodosii Spasov. Jazzanitza is a long-term author's project of the drummer and composer Borislav Petrov. Well known Bulgarian musicians such as Antoni Donchev, Vladimir Karparov, Dimitar Liolev, Lyudmil Krumov have been a part of it. The current lineup of the band includes the "young lions" of ethno jazz Zhivko Vassilev and Borislav Iliev. In Jazzanitza's third album, called "Be-Bop-Hop-Trop", Borislav Petrov created an amalgam between Bulgarian instrumental folklore and bebop music, writing original melodies over the chords of well-known bebop songs.
