Endless Pain was born at the end of 2001 from the ashes of Nuclear Storm when Max Juso (vocals) and Beppe (guitar) came together with Eddy (drums). But Eddy would soon leave when the band changed their name to Endless Pain, in an effort to permanently drop their past and start a new. Stefano Zani (guitar) joined just prior to the new name taking hold leaving only the arrival of Gigi Faglia to take over the drum slot, and Enrico Benedetti to join on bass. Endless Pain would offer a Thrash Metal style of the past, especially that of the German scene of the early 1980s (Sodom, Destruction, Kreator, and the like). Their work would naturally also drift into the styles of some of the sound masters like Slayer as well, even covering some of their songs.
September 2002 saw the release of their debut self-produced demo The Cruel Way Of War and live performances playing with Exsecratum, Hatework and other bands.
In June 2003 their full-length second demo Shotgun Carnage, would be released. Later that same year they were invited to several festival events around Italy performing with Destruction, Dismember, Tankard, Slayer, and Anthrax before releasing their debut album Born In Violence (2005). Juso would then leave the band to be replaced by Lello for De-Generation War (2008).
