"Thrash revival" is a term to describe the resurgence of thrash metal scene that was once considered dead. Bands including Municipal Waste, Evile, SSS, Sanctity and Gama Bomb have been cited as key in the "resurgence" of thrash metal in 2000s. The genre's sense of recklessness and energy has been cited as a potential reason for its resurgence. Also many bands that ended around the 90s gathered again around 2000s, bands like Exumer, Evildead, Dark Angel, Death Angel, Nuclear Assault, Defiance, Whiplash, Hirax and Possessed. Older thrash bands have continued to put out material such as Megadeth's Endgame (2009), Slayer's World Painted Blood (2009), Metallica's Death Magnetic (2008), Destruction's D.E.V.O.L.U.T.I.O.N.
