I have always admired the American heavy metal band Metallica.
They are very talented, but I don't like their individual personalities. Great group, though
I feel you on that. Metallica has been around since 1981 when Lars Ulrich and James Hetfield got together. It says something when a band lasts that long.
Yes it does. The original guitarist went on to form Megadeth
Metallica is also known as one of the "big four" in the trash metal scene. 
What are the other three?
Metallica
Metallica is an American heavy metal band. The band was formed in 1981 in Los Angeles, California, by drummer Lars Ulrich and vocalist/guitarist James Hetfield, and has been based in San Francisco, California for most of its career. The group's fast tempos, instrumentals and aggressive musicianship made them one of the founding "big four" bands of thrash metal, alongside Megadeth, Anthrax and Slayer. Metallica's current lineup comprises founding members Hetfield and Ulrich, longtime lead guitarist Kirk Hammett and bassist Robert Trujillo
Broken, Beat &amp; Scarred
"Broken, Beat & Scarred" is the forty-fifth single by American heavy metal band Metallica, and the fourth from their ninth studio album, "Death Magnetic," released on April 3, 2009.
James Hetfield and Lars Ulrich argued at length over the title of this song. Hetfield said that he did not like the title, but Ulrich was "very adamant" that it should be called "Broken, Beat & Scarred".
