Rocking On The Edge Of Time.

Deep at the Earth's Centre lay the Death Generator. Buried there from time immemorial by a long-dead race of aliens, it had at last been triggered into action . . .
For among the ruins of London, surrounded by the survivors of the recent holocaust, Hawkwind rock, their music catalysing the attacking Death Ray--a lethal concoction of high energy that insinuates it's way into the mind, tormenting every sense with demonic psychic visions. With the breakdown of the barriers between nightmare and reality, Hawkwind find themselves re-enacting the stages of a war that took place thousands of years before, in which they take the role of the Hawklords--the only potential saviours of the human race otherwise doomed to extermination in an apocalyptic battle between the forces of good and evil . . .
