The Stadium Arcadium World Tour was a 2006-2007 concert tour by the band Red Hot Chili Peppers in support of their ninth studio album, Stadium Arcadium. The band started out with a pre-tour promotional leg of dates around the world while the world tour was composed of six legs, three in Europe, one in Australia, New Zealand and Asia, and the other two in the US and Canada.
The tour was the last to feature guitarist John Frusciante, who confirmed his departure from the band in 2009. Frusciante was replaced in the band by longtime friend and musical partner, Josh Klinghoffer, who was a backing musician for the Peppers in 2007 on the final legs of the Stadium Arcadium tour, serving as an additional guitarist, backing vocalist, and performing keyboard parts. Adding an extra guitarist for the first time to their touring lineup gave the band a chance to perform songs that they were otherwise unable to play with just one guitarist.
Most shows started with an opening jam by John Frusciante and the band before the signature riff of "Can't Stop" signalled Anthony Kiedis' arrival on stage. The rest of the songs changed with each venue; however, "Charlie" and "Dani California" were usually played as the second or third songs. The set list consisted mainly of songs from the new album, Stadium Arcadium and the previous two albums, By the Way and Californication. Singles such as "Tell Me Baby", "Snow ((Hey Oh))" and "Hump de Bump" were core numbers. The band also incorporated several acoustic numbers from the recent release and the back catalogue, which gave the show both a fast and slow pace. Some of the band's more popular singles that were played often on the previous tours such as "Around The World", "Parallel Universe" and "Suck My Kiss" were rarely played. The encore of the show usually consisted of "Californication" along with a classic Red Hot Chili Peppers anthem, such as "Give It Away" or "Higher Ground", one of the band's more popular songs from the 1980s which was added to the setlist on the tour's final legs and performed for the first time since the Californication tour. "Higher Ground" was one of only two songs from Mother's Milk played on the entire tour with the other being "Nobody Weird Like Me". The band also played "Funky Monks" twice on this tour, their first and last performance leading this tour was in 1991. Two songs from Freaky Styley, "Catholic School Girls Rule" and "Sex Rap" were performed for the first time in over 15 years. The tour also marked the first time since 1991 that two of the Peppers' biggest and best known singles, "Give It Away" and "Under The Bridge", were not included in all performances leaving some fans at certain shows upset that one if not both of the songs were left out of the setlist. Of the albums 28 songs and 10 B-sides only 20 songs have been played live in any capacity, none of which were B-sides, and Hard to Concentrate was not played live until the band's I'm With You tour.
