Whitesnake continued to tour in late 2004, playing several shows across Europe and the UK. Their London concert at the Hammersmith Apollo in October was also filmed and later released as "Live... In the Still of the Night". In April 2005, Whitesnake parted ways with Marco Mendoza, due to scheduling conflicts with Mendoza's other projects. Session musician Uriah Duffy was announced as his replacement the following month. Whitesnake then embarked on another US tour, followed by a South American trek. In May 2006, the band played several shows in Japan, which were then followed by festival dates in Europe. Later in August, Whitesnake signed a European recording contract with Steamhammer/SPV. The band then released the live album "Live... in the Shadow of the Blues", which contained four new songs written by Coverdale and guitarist Doug Aldrich. Coverdale attributed this change of heart over new music to a need for "new meat to bite into" in order keep touring interesting. Preliminary work on a new Whitesnake album began in early 2007, with Coverdale and Aldrich spending considerable time writing together and refining their joint ideas. A release date was originally set for summer 2007, but the album was later pushed back to October 2007 and then May 2008. Regarding the delays, Coverdale later stated: "The recording of this album was constantly compromised by interruptions. [...] Also, to be honest, there was no real rush for us to finish the project quickly." In 2007, Whitesnake released a two-disc 20th anniversary edition of their self-titled album. Similar re-releases were also arranged for "Slide It In" and "Slip of the Tongue" in 2009. In December 2007, Chris Frazier was announced as Whitesnake's new drummer. Tommy Aldridge reportedly left to pursue "alternate musical adventures".
