The very best of Judas Priest (together with 1978's Killing Machine/Hell Bent for Leather) and the very essence of heavy metal. Perfect from the opening double punch of Freewheel Burning/Jawbreaker to the slowly grinding, hypnotic anthem Heavy Duty/Defenders of the Faith. Absolutely essential album. Highlights: every song, especially the first five (from Freewheel Burning to Love Bites)
