Query: Excellent precursor to "puppets"

This album was my introduction to speed metal back in the day. It blew me away then, and I still enjoy it today. I strongly prefer Master of Puppets, so go for that one first if you don't already have it, then come back to Ride the Lightening to see where that came from, then go back yet again to Kill Em All. All three of these albums are amazing, and all have something unique to offer. I think listening to them in reverse order helps you appreciate the earlier albums because you recognize details that will later reach their full potential on Puppets.
