Stadium Arcadium is the ninth studio album by American rock band Red Hot Chili Peppers. It was a double-album, first released in Germany on May 5, 2006, and released on May 9, 2006 in the United States on Warner Bros. Records. It produced five singles: "Dani California", "Tell Me Baby", "Snow (Hey Oh)", "Desecration Smile" and "Hump de Bump", along with the band's first fan-made music video, for the song "Charlie". In the United States, Stadium Arcadium became the band's first number-one album. Stadium Arcadium was originally scheduled to be a trilogy of albums each released six months apart, but was eventually condensed into a double album.
The album was praised for integrating musical styles from several aspects of the band's career. The album gained the band seven Grammy Award nominations in 2007 including an award for Best Rock Album and one for Best Boxed or Special Limited Edition Package. Winning four out of seven Grammy Awards, it was the most nominations that the band had garnered in their (at the time) 23 year career. Rolling Stone has included the album on its list of Best Albums of the 2000s. Kiedis attributed the album's success to less abrasive dynamics within the band, saying that the band's "chemistry, when it comes to writing, is better than ever. There was always a struggle to dominate lyrically. But we are now confident enough in who we are, so everybody feels more comfortable contributing more and more valuable, quality stuff."
After the culmination of the Stadium Arcadium tour, guitarist John Frusciante left the band in July 2009. It was his last album with the band until the release of Unlimited Love in 2022, more than a decade later.
