Fan-filmed video footage of ANTHRAX performing a cover version of the SEPULTURA classic "Refuse/Resist" on April 27 at HSBC Brasil in São Paulo, Brazil can be seen below.SEPULTURA's Andreas Kisser filled in for ANTHRAX guitarist Scott Ian at 11 shows in July 2011 while Ian spent time with his family following the birth of his first child. Kisser made his live debut with ANTHRAX on July 22, 2011 at Veltins Arena in Gelsenkirchen, Germany as part of a "Big Four" show with METALLICA, SLAYER and MEGADETH. In a letter addressed to Andreas on ANTHRAX's official Facebook page, the band wrote, "Words cannot express the feeling of love we have for you. From the first day, you were a part of the family. You were the only choice to fill in for Scott and that decision proved to be the right one. Thank you for being you, we miss you already. Have a great tour with the mighty SEPULTURA." Speaking to RockAAA at the U.K. installment of the Sonisphere festival, Andreas stated about what it was like to receive the call asking him to fill in for Ian, "It was amazing. ANTHRAX… I mean, all the four bands here [METALLICA, SLAYER, MEGADETH and ANTHRAX] are the DNA of my guitar playing. I started listening to them, the heavier music, and I wanted to play the same. They were my teachers. And to be here, it's just… I don't think even a dream. I [couldn't have] dreamt something like that to happen. And the good thing is it's a very positive situation. Scott is not sick, [he doesn't have a] a broken arm or something like that. It's very, very positive. It couldn't be better. So I'm very honored to be here, by these guys, and jam. We're having fun." Added ANTHRAX bassist Frank Bello: "Andreas locks in with the band like he was always here. So there's not a thought to playing; we don't have to worry. It's nice to go on stage and not have to worry. That's the last thing we wanted to do. And he's good, he's so locked in, even with the cues, the vocals — everything. Boom! It's ANTHRAX." Regarding how Kisser came to fill the temporary guitarist slot, Ian previously said, "We chose Andreas because we feel he can do the gig better than anyone. He has the fire, the attitude, and the crushing right hand to do the gig. I've played with Andreas at the Roadrunner 25th-anniversary show, and I've gotten up and played with SEPULTURA and we are kindred spirits. We both play every show like we're going to jail the next day, like it's the last show we'll ever play. He has what it takes and he has the experience and history to fucking bring it and make these ANTHRAX shows something special."
