Justin Lee Collins continues the story of British heavy metal and reaches 1977, when some fans thought bands like Black Sabbath and Deep Purple had become overblown, pompous and out of touch with their audience, and punk came along to change everything. In this concluding part, JLC explains how the new wave of British heavy metal combined the spirit and DIY attitude of punk with the original metal concepts, hailing an era that would produce international stars such as Iron Maiden, Def Leppard and Motorhead. It was a popular musical movement to rival punk, with hundreds of smaller bands all over the country like Saxon, Diamondhead, Venom, Angel Witch and all-girl metal band Girlschool. And while the 1980s would see a decade of metal dominance in popular music, the British bands were eventually usurped by their American counterparts. The series includes rare BBC sessions and archive material, plus brand new interviews with members of Black Sabbath, Motorhead, Judas Priest, Deep Purple, Iron Maiden, Def Leppard, Budgie, Saxon, Diamondhead, and many more.
