Formed in 1981 by guitarist/vocalist James Hetfield and drummer Lars Ulrich, Metallica would go on to become the biggest heavy metal band in the world with a career spanning over 30 years with an estimated 100 million records sold worldwide. The group's initial lineup consisted of Hetfield and Ulrich alongside lead guitarist Dave Mustaine and Cliff Burton (who replaced original bass player Ron McGovney) but due to personality issues Mustaine was replaced by, the then Exodus guitarist, Kirk Hammett. Mustaine went on to form the iconic band Megadeth, while the newly strengthened Metallica focused on their first release, Kill 'Em All in 1983.
