The band then took a break from touring in 2010 to concentrate on writing a new album. They also signed a new recording contract with Frontiers Records. In June, Uriah Duffy and Chris Frazier left Whitesnake, with latter being replaced by former Billy Idol and Foreigner drummer Brian Tichy. Michael Devin, formerly of Lynch Mob, was revealed as the band's new bassist the following August. In September, Timothy Drury announced his departure to pursue a solo career. "Forevermore", Whitesnake's eleventh studio album, was released on 25 March 2011 in Europe, followed by a North American release on 29 March. Once again produced by Coverdale, Aldrich and Michael McIntyre at Lake Tahoe, "Forevermore" reached number 33 on the UK Albums Chart, and number 49 on the "Billboard" 200. On the Independent Albums chart it peaked at number ten. The record's highest chart position was in Sweden at number six. As of May 2015, "Forevermore" has sold 44,000 copies in the US. Thom Jurek of AllMusic gave the album a positive review, in which he proclaimed: ""Forevermore", despite its tighter arrangements and more polished production is Whitesnake at its Brit hard rock best." A supporting tour kicked off in New York on 11 May 2011. After several dates in the US, the tour continued across Europe. During the band's performance at the Sweden Rock Festival, they were joined onstage by former guitarist Bernie Marsden. In October, Whitesnake played the Loud Park festival in Japan. On the tour, the band were accompanied by keyboardist Brian Ruedy. That year, Whitesnake also released a live recording of their 1990 Monster of Rock concert at Castle Donington.
