With Dave’s retirement announced we have to go back to when he was in the band, and Metallica themselves remastered this recording back in 2015 making it a really cool piece of history. Originally from 1982 and had Ron McGovney on the bass for this recording, who was the original bassist, pre-Cliff even. So this really is the beginning.

I won’t cover the split between Dave and the rest. There’s enough on wikipedia. But I will say that the track here has been itself really controversial. Dave wrote it in his band before Metallica, and re-recorded it with Megadeth, his band after, with Metallica reworking it into The Four Horsemen. And they sound almost identical. But Dave didn’t get credit in Kill 'em all which had kept the fued going for many decades, with some closure in recent years. It also wasn’t only this track with royalties being the sticking point

But safe to say they’ve all made enough money now to say it’s history and move on. Because without this track there may never have even been a Metallica or Megadeth
