Kill 'Em All is forty! Metallica's stunning debut was released on 25th July 1983, and as a statement of intent they don't come much better than this. Lightning licks switching to chugging riffs, melodic clean guitars, breakneck wah solos, choruses that a crowd could easily sing along to - the DNA of Metallica's evolution can all be heard here.
