Metallica-Ride The Lightning (1984)

If their debut album had subtly revealed the musical direction Metallica was heading in, their second album left no doubt about it. The intensity and raw power remained in this second release, but they also became more versatile, creating more complex and intelligent music. This shift is evident in the epic and brilliant "Fade to Black" and "Call of Ktulu", two tracks of great instrumental complexity that border on progressive sounds. However, glimpses of the frenetic thrash metal of their first album still lingered in the incredible and intricate "Creeping Death", "Fight Fire with Me", and "For Whom the Bell Tolls". This second album would put Metallica's name on the lips of millions of heavy metal fans around the world and pave the way for them to explore new horizons with great works in the years to come.
