I have just watched the first two parts of a four part series entitled Heavy: The Story Of Metal that is absolutely outstanding. All the major players are interviewed with some great footage. Part one is an introduction and part two looks at the new wave of British metal in the 1970s featuring Iron Maiden, Judas Priest and Def Leppard.
I appreciate that this is old news to the Metal Heads, but this review is terrific.
P.S. Bruce Dickinson could belt them out!
