If Metallica's 1983 "Kill 'Em All" wrote the book on thrash metal, then their sophomore release "Ride The Lightning" re-wrote the book on what metal was capable of. It was simply revolutionary at the time. Since "Kill 'Em All", the members of Metallica had seriously expanded their talents, technique and their approach with this groundbreaker. Every track offers something new, and experimental. The instruments aren't the only improvement. Hetfield's lyrics are much more personal, and conscious. The extended instrument arrangements blow everything from "Kill 'Em All" out of the water. Tracks such as "Fade To Black" and "The Call of Ktulu" were absolutely phenomenal works, untouched by the standards of 1984. And although it's up for debate, Hammett's guitar solos are my favorite on this album. Check out the two and a half minute guitar solo on "Ride The Lightning", that left my body covered with goose bumps as a teen, and still does to this day. Other highlights include "Fight Fire with Fire," and "For Whom the Bell Tolls". This album rocks in epic proportions.
