Other projects
Rossdale appeared in Blue Man Group's "The Current" and is featured in its video. This song was used in the ending credits of Terminator 3: Rise of the Machines.
In 2004, after Bush had been on hiatus for two years, Rossdale formed Institute. Their album, Distort Yourself, released 13 September 2005, achieved moderate success and the single "Bullet Proof Skin" was used in the motion picture Stealth. In an interview published in November 2008, Rossdale noted that the Institute record was, "for all intents and purposes, a solo record. It was just a bad marketing decision to call it something else."
Rossdale's first solo record, entitled Wanderlust, was released on 3 June 2008. Gwen Stefani, Rossdale's then-wife, sang background vocals on the track "Can't Stop the World", with other vocalists on the album including Shirley Manson, Katy Perry and Dave Stewart.
On 1 April 2008 the first single from Wanderlust, "Love Remains the Same", was released through digital retailers. It entered the Billboard Hot 100 at number 76, rising to 27 in October 2008, giving Rossdale his first top 40 hit since the days when he fronted Bush. Rossdale mounted a full-scale solo tour in spring 2009. Of the album's title, Rossdale said, "I just liked it because it's kind of sexy enough, it's powerful, it's one word. Wanderlust sums up that desire for music and for singing and performing and this life."
Rossdale also provides the vocals for the Apocalyptica song "End of Me", which is the lead single from their 2010 album, 7th Symphony.
Rossdale was a judge for the tenth annual Independent Music Awards to support independent artists' careers. In 2013, Rossdale was awarded in the Ivor Novello Awards, for International Achievement in Songwriting, which was presented to him by Chris Martin. On 27 October 2017, Rossdale sang with Linkin Park at their special memorial concert in memory of vocalist Chester Bennington. He performed the song "Leave Out All the Rest."
