Metallica are not just the biggest metal band on Earth, but one of the biggest bands in all of recorded human history. This notion is not lost on Megadeth's David Ellefson, who spoke glowingly of the band while expressing that his own group, along with every other metal band, "owe everything to Metallica."
There's quite the history between the two legendary thrash groups, as all fans know. Dave Mustaine began his career in Metallica's ranks before being jettisoned in 1983 as the band was on the verge of recording their debut record. For decades, there was bad blood between the two sides, but it's all in the past now as Mustaine and Metallica's members have reconciled.
