Metallica's sophomore album, "Ride The Lightning" certainly showcases some interesting and classic thrashers. It's hard to imagine what the metal community nowadays would be like without gems like this album. It seems that this album seemed to be an overlooked one in Metallica's early catalogue, considering "Kill 'Em All" is generally considered the birth of thrash metal, "Master of Puppets" is regarded as Metallica's magnum opus, and "...And Justice For All" got Metallica some mainstream attention with the music video for "One".
