Auf der Maur was featured on neither "Machina/The Machines of God" nor "Machina II/The Friends & Enemies of Modern Music" (2000) as Wretzky's remaining bass duties were assumed by Corgan during recording sessions, but she played with the Pumpkins during the "Machina" tour from December 1999 to December 2000. The tour covered North America, Japan, Europe and South Africa and was described by Auf der Maur as "very ambitious". Reflecting on the tour, she said: "they would always be changing arrangements and keys of songs. The work ethic of the Pumpkins is so full-on and so demanding ... joining band was just intense work, much more about work than about emotional experience". She performed at various shows, including the band's final television performance on "The Tonight Show with Jay Leno" and the band's final show at the Cabaret Metro in Chicago on December 2, 2000, as well as appearing in the band's music videos. Smashing Pumpkins broke up at the end of the year 2000.
