Cornerstone of the concept of this collective are the ideas of RadostbBand group.

"Radost was formed at the end of 2008 when several Russian musicians started to analyse contemporary trends in music and explored ways of developing a new musical culture. Today the Radost’s experience is enriched with flavours and nuances of other musical cultures, and they consciously use musical elements that a European listener hasn’t heard for several centuries." (Russia & India Report "Rossiyskaya Gazeta")

"The ensemble was formed by russian musicians, who take part in a numerous musical projects, including cooperation with Oleg Lundstrem Big Band and other world famous musicians, playing in different genres & styles, and playing in bands performing pop music." (Festival "Art-Obstrel")
