Worlds Within Worlds (Part I and II) is one of the most important improvised jazz-based recordings of all time. Released in 1971 it sold just a handful of copies, but has become a keystone in the development of experimental and ambient sounds - originals now fetch £1000+.Built up using layers of treated and slowed field recordings with Derek Bailey and Evan Parker improvising, WWW offers listeners a mesmerizing sonic experience that remains years ahead of its time. This pressing features a new gatefold sleeve (Kirchin hated the original sleeve), with images of Kirchin, his original field recording tapes and notes by WWW fan Thurston Moore. There are just 1500!
