Thrash fucking rules till death, its one of my favorite metal genres. Some kings of the genre include Bands like Megadeth, Exodus, Testament, Kreator, Slayer, Destruction, Annihilator, Coroner, and Metallica.
Regarding Metallica...
According to new interviews with Metallica, they are trying to embrace thrash again and Kirk Hammet stated they had wrote some songs that are so fast it almost burned their wrists off. The two new Metallica songs that have been leaked have been deleted from the album, and they are tuning back to E. Lets hope they can fix that guitar tone though.
