In 1986, metallica released their third, and probably best-ever album entitled Master of Puppets. This album had great production and recording, a smooth melodic tone laced with heavy riffs, and James signature voice. The guitars are complex and heavy, the songs are long ballads. Everything about this album is good. Sanitarium, Leper Messiah, Battery are excellent songs with great riffing and wonderful harmony. Excellent cruisin' music.
