On their current comeback run, Pantera have been bringing out famous friends from across the metal spectrum when they perform their iconic anthem "Walk" — everyone from Testament's Chuck Billy and Sepultura/Soulfly founder Max Cavalera to black-metal pioneers Attila Csihar and Satyr, of Mayhem and Satyricon, respectively.
One of the latest heavy-metal stars to join the fun is Anthrax vocalist Joey Belladonna, who jumped onstage to chant "Re! Spect!" during Pantera's August 8th stop in Syracuse, New York. Belladonna's bandmate Charlie Benante is, of course, drumming with the groove-metal titans in the place of his longtime friend, the late, great Vinnie Paul, so the cameo also marked a particularly cool "Panthrax" crossover.
Watch fan-filmed footage above. The Pantera tour continues August 12th in Toronto, Canada.
