Lucifer's Friend is a German hard rock band, formed in Hamburg in 1970, fronted by British vocalist John Lawton (of Uriah Heep), guitarist Peter Hesslein, bassist Dieter Horns, keyboardist Peter Hecht, and drummer Joachim Reitenbach. The group was an early practitioner of heavy metal and progressive rock; they also incorporated elements of jazz and fusion into their music, especially in their fourth album Banquet of 1974. Evolved from Asterix and comprised of 3/4 of The German Bonds, the group officially disbanded in 1982. They briefly reunited (1993-1997) as Lucifer's Friend II, releasing one album before disbanding once again. In 2015 they have reformed again. The band features core original members John Lawton, Peter Hesslein and Dieter Horns.
''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.
