it was announced that Tim Mallare would not take part in this tour. Replacing him for the tour was former Hades drummer Ron Lipnicki. A few weeks later, the band announced that Mallare had left permanently and Lipnicki was his replacement. In the summer of 2005, Overkill organized their first US west coast tour in more than ten years, playing Western Canada to Southern California. The tour was such a success that the band was added to the 2006 Gigantour bill, as second stage headliners, marking Overkill's first nationwide US tour since 1994. Now with the Bodog Music label, the band rejoined forces with Jonny and Marsha Zazula, previous owners of Megaforce Records, who are now part of the Bodog Team in the United States. Overkill released its 15th studio album, Immortalis, on October 9, 2007. The album featured the lineup of founders Bobby "Blitz" Ellsworth and D.D. Verni, guitarists Dave Linsk and Derek Tailer, and new drummer Ron Lipnicki. Lamb of God vocalist Randy Blythe contributed vocals on the song "Skull and Bones". Return to popularity and departure of Lipnicki (2009–2017) On October 30, 2009, it was reported that Overkill had inked a multi-album deal with Nuclear Blast Records. The band's 15th album, Ironbound—which is described as a true "thrashter-piece"—was released on February 9, 2010. The album marked something of a "comeback" for Overkill after years of lackluster record sales and a decline in popularity in the U.S. since the mid-1990s; it was also the band's first album to appear on the Billboard 200 chart since 1993's I Hear Black, peaking at number 192. The band happened to be playing at Times Square in New York City on May 1, 2010, as part of their Ironbound tour when someone nearby attempted unsuccessfully to blow a car up using fireworks. The show proceeded without interruption, but some ticket holders arriving late were prevented from entering the theater by police responding to the incident. Overkill toured for almost two years by promoting Ironbound; it started with a European trek in February 2010 (supported by Suicidal Angels, Savage Messiah and Cripper), followed two months later by a U.S. tour with Vader, God Dethroned, Warbringer, Evile and Woe of Tyrants. The band toured the U.S. again in the fall (this time with Forbidden, Evile, Gama Bomb and Bonded by Blood), and then did a European run in March 2011 with Destruction, Heathen, After
