The Greatest Hits tour was the fifth worldwide concert tour by Icelandic musician Björk. It was launched in support of the release of her Greatest Hits album, her box set Family Tree, and to coincide with the release of her Live Box collection. The tour was supposed to take place one year earlier, but it was delayed as Björk gave birth to her daughter. The first dates of the tour were announced just two months after the birth. The tour kicked off with two shows in London on May 24, 2003, and ended with a rescheduled performance in Toronto on September 3, 2003. The tour visited Europe, Asia and North America with 28 shows in total. Björk wore outfits and creations from Jeremy Scott, Alexander McQueen and Shoplifter.

The Volta tour was a tour by the singer Björk that focused on her album, Volta. Overall, 48 songs were done on the tour focusing on many tracks from Debut through to Vespertine, though mostly from Medúlla and Volta, the former of which did not receive its own tour. The tour band consisted of drummer Chris Corsano, musician Mark Bell, pianist Jónas Sen, musician Damian Taylor and a 10 piece female Icelandic brass section. Many of the songs evolved considerably during the tour, including "Innocence" which was re-done so as to incorporate brass elements. Live performances of the track "Declare Independence" made heavy use of the ReacTable, an electro-acoustic music instrument with a tabletop Tangible User Interface, which is played by Damian Taylor. The Tenori-on was used heavily in performances of "Who Is It". A live DVD and CD of the Volta tour was released as part of Voltaïc. The tour was Björk's first in four years and saw her play countries that she had not played in over ten years.
