Handmade Paper Pipe is the collaborative project of Danish improviser Claus Haxholm and eclectic Italian sound-maker Renato Grieco. These two set pieces are the result of mutual manipulation of each other's voices and archival materials. Not many words were spoken during the process and the result covers a many topoi of modern experimental palette and noteworthy is the presence of low frequencies that sometimes even touch the territories of a hypothetical abstract vocal dub.
