''Mean Machine'' is the eighth album by Lucifer's Friend. On this album the band returns to their heavy metal roots, albeit with less of the Hammond organ found on the first album. However, by this time the band had lost its core following years ago and it was too late to recover. Lucifer's Friend lasted a year after the album's release and then finally broke up. John Lawton would join the hard rock bands, Rebel and ZAR. Lucifer's Friend would reunite in 1993 and would release SumoGrip in 1994 and would breakup for the final time in 1996.
