Metallica are truly one of the forces to be reckoned with in their genre of music whether you call it Metal, Heavy-Metal or Thrash is of little importance, they're one of the greats. While everyone has their own opinion of the band and what would become a lengthy career you absolutely cannot take away their achievements and the great music they have put out. Metallica already proved themselves to be a great band with their debut album Kill `Em All which has that early real raw and unpolished sound that makes it a fan favorite. 1984's Ride The Lightning expands on the formula of Kill `Em All and shows a bit more maturity, I mean the debut is great and it shows a lot talent it also shows a lot of anger from some seriously p***** off teenagers. You can see a certain progression, a development from the first album and they were becoming more and more the band that would release Master of Puppets. Ride is a dynamic and solid album all the way through, it also features tight musicianship and a lot of youthful aggression that's still very much present more than 25 years later.
