In early November 2020, the singer teamed up with the choir she was a member of as a teenager to unveil new versions of her tracks Cosmogony, Sonnets and others. Cosmogony originally appeared on Bjrks 2011 Biophilia album, and this alternate a cappella rendition was conceived more recently during Bjrks Cornucopia Tour with the Hamrahlid Choir in 2019. Composed by Bjrk and set to the words of an E. E. cummings poem, Sonnets was originally a choral piece taken from her 2004 vocal album Medlla.
