Ватра - Як Я Спала На Сені
it is Ukrainian folk song. played by one of their most famous VIAs, Vatra. it's taken from their only LP, released first time in 1974.
all songs on LP are arrangements of local folk music. though there isn't many western influences, you can find some funkier parts from two songs. particularly i like this track with psychedelic jew harp breakdown. actually first track has also jew harp breakdown. also track "Ivana Kupala" has good groovy intro, but it's something for serious Melodija collector.
quick look through wikipedia told me that they were actually folk-jazz-rock group. even though it says on sleeve that tracks are arranged by B. Kudla, these are mostly arranged by previous leader M. Manuljak, who was repressed by officials for not making any cooperation with them.
