Amon Amarth vocalist, Johan Hegg was unable to join his band at their show in Plymouth, England, last night (January 17), due to losing his voice the night before. Since he was unable to perform, the band played a mostly instrumental set, but during the song “Guardians Of Asgaard” they were joined by guest vocalist, Jill Janus (Huntress). Some fans were also invited onstage to sing a few songs, as well.
Check out this fan filmed footage of Janus performing “Guardians Of Asgaard”:
