The electroacoustic album Klesajúce klenby is a duo project of Ján Boleslav Kladivo, a legendary persona of the Slovak alternative scene and enigmatic TJ Vjuga (literary-sonic pseudonym of Julo Fujak), who are moving on the boundary of differential sound arts, free improvisation and experimental music. On their recording there are continuously intertwined digital electronic and acoustic instrumental areas, which in mutual symbiosis create impressive ambient sound fields, referring to various contemporary (out) musical worlds.
