Folklore group Radost (gladness) from Kamenný Újezd near České Budějovice was founded in 1986. Nowadays, Radost has eight dance pairs. In 2006, woman choir came into being and started to co-operate with Radost.

Radost is incorporated with "Folk bagpipe music Bedrník" which accompanies the dance group everywhere.

Very important for the group are also children, because the group includes a child group with its own music.

The repertoir contains dances and songs not just from Doudlebsko, the ethnographic area where the group belongs, but from the whole South Bohemia.
