During this long weekend two chamber concerts in the Masquerade Hall await the viewers of the IMF Český Krumlov 2013: on Thursday 25/7 the Prague Guitar Quartet will play and on Friday 26/7 violist Jitka Hosprová with the Prague Radio Symphony Orchestra Collegium will perform. Saturday 27/7 will be dedicated to Russian music as well as Russian culinary specialities – the Russian Evening in the Brewery Garden is on the programme. The main star of the evening will be the group Turetsky Choir, whose performances are a combination of singing, dramatic art, and perfect choreography. It is regarded as one of the most successful Russian groups and its concerts are regularly described as the cultural event of the year. All the ten soloists have classical music education and the voice range of the whole group is four and a half octaves. Therefore they are not afraid to perform any composition or music experiment, they always sing live and in close contact with the audience. After the concert of Turetsky Choir the social part of the evening will follow, during which the Czech-Russian folklore group Vltava Cossacks will perform.
