Sure, there were a few demos before this, but 'No Life Til Leather' is what got the ball rolling with Metallica in the early days. This was the demo that got into the hands of Johnny Z, got them signed and eventually led them to get in the studio to record 'Kill Em All.' Although the songs didn't change much from the demo (other than The Mechanix), it's a great representation of what was happening in the early 80's thrash metal scene. Plus, Mustaine's leads on this? Come on...He rips. In this episode we read some fan mail and discuss the demo cassette that started it all.
