Bulgarian folk rock groups

Balkandji is a folk metal band from Bulgaria. They freely mix traditional Bulgarian music with hard rock and heavy metal. As Bulgarian folk music is very complex, in Balkandji songs odd time signatures and constant time signature changing are very common. They create a characteristic blend of melodies taken from the Bulgarian folklore with heavy guitar riffs.

Isihia (, "hesychia") are a Bulgarian folk rock music band founded in 2000, the style of which unites elements of Bulgarian folklore and Hesychast Christian chant of the 14th century to create an atmosphere of Balkan spiritual mysticism. Many of the group's songs cover topics of the medieval history of Bulgaria, mostly the period of the Ottoman invasion of the Balkans and the attempts on its repulsion and the early Ottoman rule of Bulgaria, i.e. the 14th-15th century, but also other moments of hardship such as the tragic Battle of Klyuch of 1014.
