During Anvil’s October 27 show in Stockholm, Sweden, the band were joined onstage by guitarist Mats “Mappe” Björkman (Candlemass) and singer Messiah Marcolin (ex-Candlemass) for a performance of “Metal On Metal.” You can see fan-filmed footage of that below. Marcolin told Blabbermouth the following:
“It’s the first time in 16 years me and my old friend Mats Mappe Björkman from CANDLEMASS [were] together on the same stage. We are both old ANVIL fans since being teenagers. Since we are friends with ANVIL they invited us up on stage and it was great fun!”
