1980s THRASH METAL
WHEN DAVE MUSTAINE WAS FIRED FROM METALLICA IN 1983, HE TOLD THE BAND TO NOT USE HIS SONGS; THEY DIDN'T LISTEN, AND RELEASED "KILL 'EM ALL" FEATURING "THE FOUR HORSEMEN," A REVISED VERSION OF THIS SONG WRITTEN BY DAVE MUSTAINE AND RELEASED ON MEGADETH'S 1985 ALBUM "KILLING IS MY BUSINESS... AND BUSINESS IS GOOD!"
