Apollo was released in February 2006. In June 2006 Coverdale signed a new record deal with Steamhammer Records. The first release under the new contract was the double live album Live: In the Shadow of the Blues (released 27 November 2006); the album also contained 4 brand new studio tracks written by Coverdale and Aldrich. In 2008, the band (with a new bassist and drummer) released its first new studio album in over 10 years titled Good to Be Bad. The band toured the album extensively. Also in 2008, Whitesnake embarked on a European Tour as part of a double bill with fellow Yorkshire rockers Def Leppard. In 2009, Whitesnake toured with Judas Priest on the British Steel 30th Anniversary Tour. On 11 August 2009 Whitesnake were playing a show at Red Rocks Amphitheatre in Morrison, Colorado when Coverdale suffered some kind of vocal injury. After seeing a specialist, it was announced on 12 August 2009 that Coverdale had been suffering from severe vocal fold edema and a left vocal fold vascular lesion. The remainder of the tour with Judas Priest was cancelled so that this injury would not worsen. In early February 2010, Coverdale announced that his voice had seemed to have fully recovered from the trauma that sidelined him and the band on the Priest tour. He stated he had been recording new demos, aiming for a new Whitesnake album, and that on tape his voice was sounding full and strong. The studio album Forevermore was released on 25 March 2011, with Aldrich and Beach on board. In May 2015, with the addition of guitar virtuoso Joel Hoekstra (formerly Of Night Ranger) the band released The Purple Album with cover versions of the songs that Coverdale had originally performed with Deep Purple. It was followed by a tour. In 2016, Whitesnake embarked on the "Great Hits" tour, in selected cities in North America and Europe. In 2022, the band began their COVID-delayed farewell tour with European dates kicking off in Dublin on 10 May 2022, but were able to continue only until their date in Croatia on 2 July 2022. After cancelling the last 11 dates of the European leg of the tour due to health problems affecting various band members including Reb Beach, Tommy Aldridge and Coverdale himself, Whitesnake subsequently cancelled the entire 2022 North American leg of its Farewell Tour as Coverdale was forced to deal
