A collection of sound of the children's musical "Kurtchen's Hat" which was adapted for the stage in 1985. The music is composed by Bun Itakura and Kazuto Shimizu of Chakra, Daisaku Kume of Prism, and other members such as Banana, Tatsuro Kondo, Jun Aoyama, and Reichi. Total 6 tracks of 45 rpm specifications that show thrilling/rhythmic, and serious musicality even though it is for children. Full of wired songs that are said to be their true value include highlights of strange dance song "Neighborhood is the Best in the World" and the thrilling experimental fantasy "Forest of Thorns". Amazing. It's a hidden master work that people who saw it live at the time say that the impression of the music remains.
