Extremities, dirt and various repressed emotions was always my favourite Killing Joke album so this is a real special treat for me - I just got this delivered from Play.com.

Inside Extremities, Mixes, Rehearsals & Live

This is a fan’s dream come true! A double CD of Killing Joke material taken from the band preparation for the “Extremities” album, rare mixes, a TOTALLY unheard track “The Fanatic” and a full live show from the Extremities tour.
