In August 2004 , Björk performed the song " Oceania " at the Opening Ceremony of the 2004 Summer Olympics in Athens . As she sang , her dress slowly unfurled to reveal a 10,000 square foot ( 900 m ² ) map of the world , which she let flow over all of the Olympic athletes . The song " Oceania " was written especially for the occasion and features the talents of Shlomo , a Leeds-based beatboxer , and a London choir . An alternative version of the song began circulating on the Internet with additional vocals by Kelis . It originally appeared on the promotional " Oceania " single released to radio stations and later became available to the public as a B-side of the " Who Is It " single , which charted at number 26 in the UK . This was followed in early 2005 by " Triumph of a Heart " , charting at number 31 . A video for the potential next single , " Where Is the Line " , was filmed in collaboration with the Icelandic artist Gabríela Friðriksdóttir in late 2004 . This was initially a sequence from an art installation movie of the artists but was released exclusively on the '' Medúlla Videos '' DVD as an official promo for the track
