Crass records' big KUKL-section is the "official" KUKL-site.
A whole page of KUKL, Purrkurr Pillnik (or however you're supposed to spell it) and Theyr. Includes picture-discographies to every band and a very exclusive KUKL-biography.
Pomegranate has got some pictures of KUKL at her brilliant ftp-server. Just follow the folders.
Contains a discography, pictures, downloadables, links and a really cool design! Recommended!
