On December 3, 2008, the band announced on their official website plans of a tour and a new album. They stated,
"As most of you saw from our little iChat, we have decided to go on tour next year while continuing to work on our album. We are working on tour dates now and can't wait to get out there and play for all of you – it's been too long! We'll announce tour dates soon so be sure to check back for updates. Have a safe and happy holiday and we'll see youon the road in 2009!"
The tour was officially announced in January 2009 by MTV News. Stefani cited the reason for tour was to perform their favorite songs and explore new musical directions. A survey on the band's website complied fan's favorite songs that have a possibility of being performed on the tour. During an interview with guitarist Tom Dumont, he explained the tour will have A Clockwork Orange theme, saying,
"Gwen came up with the Clockwork Orange thing—she started getting into the visuals of those modernist movies from the 60's. We've been looking at tons of art and it's like this space-age modernism from that decade—it's retro and modern at the same time, so we're building this crazy stage set that has that vibe. We have a bunch of really great artists doing t-shirts and posters that echo that. There's a whole look for the tour even though there's not an album yet."
It was also revealed that the group will give away their entire music catalog to spectators who purchased high level tickets. The group appeared on The Today Show, American Idol, The Ellen DeGeneres Show, Jimmy Kimmel Live! and Gossip Girl to promote the tour. This tour should not be considered a reunion tour, because No Doubt stated it is not a reunion since the band had never broken up.
