In 1997, the release of "Homogenic" was accompanied by a short promotional stint in clubs with Mark Bell before starting a worldwide tour. The tour was extended to 1998 after plans for a North American leg with Radiohead were canceled due to staging and production difficulties. During the promotion of the album, she also performed "Bachelorette" at the 1997 MTV Europe Music Awards and during an appearance at "Saturday Night Live". After receiving a Best Original Song nomination for "I've Seen It All", Björk performed the song at the 73rd Academy Awards, while dressed in her swan dress. To promote her fourth album "Vespertine" (2001), Björk embarked on a worldwide tour of opera houses and theaters, backed by a 54-piece orchestra. The following year, Björk became the first female artist to headline the Coachella Valley Music and Arts Festival. In 2003, the singer performed at several European festivals and North American arenas with her Greatest Hits Tour. While there was no tour performances for the singer’s fifth studio album, "Medúlla" (2004), Björk performed "Oceania" at the 2004 Summer Olympics opening ceremony, for which the song was commissioned, while in 2005, the singer performed at the Live 8 concert in Chiba, Japan.
