Swedish lo-fi electropop act 50 Hertz will contribute a track to the upcoming Björk remix/cover album "Army of me", coming out later this month on her own One Little Indian Records will all proceeds from sales being donated to UNICEF. The tracklist was hand-picked by Björk herself, so they consider it a great privilege to be included. The selection will be billed "50 Hertz featuring Slagsmålsklubben and Häxor och Porr" as members from both bands contributed to the recording.
