Kings of Thrash is an American band rooted in the thrash metal genre, a subgenre of heavy metal characterized by its fast tempo and aggression. Formed by former Megadeth members David Ellefson (bass) and Jeff Young (guitar), the band revisits and performs classic thrash material, particularly from Megadeth's early albums like Killing Is My Business… and Business Is Good! and So Far, So Good… So What! .
