Two singles were released from '' Medúlla '' : " Who Is It " and " Triumph of a Heart " , both charting inside the top forty in the United Kingdom and the top ten in Spain . Björk further promoted the album by performing at the 2004 Summer Olympics opening ceremony , along with '' Friday Night with Jonathan Ross '' and other television and radio shows . Other than these few performances , no concerts or tours were arranged to promote '' Medúlla '' , as Björk thought it would be too difficult to play the songs live . In 2015 , the album was adapted into an opera at the Brussels opera house La Monnaie by Sjaron Minailo and Anat Spiegel
