Ever struggling with line-up problems, Paul "Woody" Woodfield took over on lead guitar for studio and live duties in early 2001, whilst Stafford Glover took over on bass (from the departing Barrett, who left to concentrate on To-Mera) and Desecration's Ollie Jones was added to the line-up as permanent second guitarist. In early 2006, Phil Vane once again returned to the band after living in Switzerland for six and a half years. Zac O'Neil also left the band, to be replaced by Mic Hourihan (of Tigertailz). In 2007, ENT toured the US with grindcore band Phobia and released a split recording with Driller Killer through French label Osmose. The following year the band released a split 7-inch with Trap Them (released on Deathwish Inc.) to coincide with their joint US "West Coast Distortion" tour, which culminated at the 2008 Los Angeles Murderfest. In amongst playing shows worldwide, including Indonesia, Russia, Hungary, Slovenia, Romania, Finland, Germany, Estonia and at the Obscene Extreme Festival in the Czech Republic, ENT recorded their next album, "Law of Retaliation" which was released in early 2009 by Osmose in Europe, MCR Company in Japan, and Deep Six Records in the US. "Terrorizer" described it as "a rabid, intense and gleeful return to explosive, hyper-speed hardcore punk insanity". The band continued to tour with shows throughout 2009 in Europe and a third Japanese tour, this time with Slang.
