Folk group "DrevA" was founded in 1989 as a branch of the theatre "Perekriostok" and specialised in Russian folk and urban songs and music up to this time. The repertoire of the group is built on the materials of the expeditions in the different regions of Russia: Belgorod, Voronezh, Briansk regions and also in the Cossak stanitsas of Don and Kuban. The group mastered the manners of singing of the different regions. For example, Bryansk tradition of singing is mainly female. This region is the place where the most old pagan songs are still kept. Belgorod tradition is mainly female too, but there exists archaic male wind-instrument, in Russian "caluka". It is made from dry stalk and the sound of this pipe instrument remind of wind howl. The Don and Kuban tradition of singing is the male as a rule. These songs are not so old as Southern and Western, and singing is often accompanied by playing on Russian accordion, balalaika, guitar, drums, hurdy-gurdy, tambourine. The wonderful feature of Cossak songs is upper soaring treble voice. Repertoire of "DrevA" includes unique Cossak romances recorded in stanitsa Oust-Buzulook of Don region.
