Head as well as the partial resemblance of "Renewal". Gosdzik and Cangelosi left in 1996 and were replaced by Tommy Vetterli (formerly of Coroner). This new line-up saw Reil return. Kreator continued to experiment producing Outcast and Endorama, with ambient and gothic influences, incorporated samples and loops. Petrozza employed different approaches for singing, and the albums retained the groove metal influences. However, the record sales went down and by the end of the 1990s the band reached commercial and critical nadir. Despite that, Mille Petrozza was quoted stating: "For us, success doesn't define in record sales. So all our albums have been successful for us, because we've achieved what we were aiming for...". Return in style (2001–2009) In 2001, with new lead guitarist Sami Yli-Sirniö, Kreator released their "comeback" album Violent Revolution, which saw the band returning to their classic thrash metal style. Despite containing a lot of melodic and so called "Gothenburg metal" riffs, Violent Revolution was praised by fans and critics alike and benefited from the 2000s thrash metal revival movement, led by bands like Overkill, Slayer, Megadeth, Exodus and Testament. The tour was extremely successful and introduced Kreator to a younger generation of metal fans. Yli-Sirniö, who lived in Germany, was known to be a good guitar player, so the band recruited him. A live album Live Kreation and live DVD Live Kreation: Revisioned Glory were released in 2003, and a new studio album - emphasizing more on the Gothenburg influences – Enemy of God was released in 2005. This album also saw a special edition re-release in 2006 called Enemy of God: Revisited. In early 2006, Kreator toured North America with Napalm Death, A Perfect Murder, and The Undying. There was a joint headline European tour with Celtic Frost in 2007 with support from Watain, Kreator were to tour 2008 with King Diamond, Leaves' Eyes, and Cellador, however, the tour was canceled due to back issues with King Diamond. In March 2008, the At the Pulse of Kapitulation DVD was released, featuring Live in East Berlin and Hallucinative Comas on one disc. Both had previously been available on VHS only and were long out of print. The band had also begun working on their 12th full-length album in late 2007/early 2008 and began recording in July 2008. Recording for the album, dubbed Hordes of Chaos, was wrapped up in late August, with the album being released
