Brazilian/American metallers SEPULTURA were joined by legendary guitarist Steve Vai on stage during their May 9 performance at the Rock In Rio USA festival in Las Vegas, Nevada.
A four-minute video clip featuring behind-the-scenes footage from the collaboration can be seen below.
Asked how it was playing with Vai, SEPULTURA frontman Derrick Green told Natalia Britt of California Rock News: "This was a complete honor jamming with Steve. He's a legend, and it was magical to see him play and to be able to perform with him together was an experience I never imagined."
He continued: "We have the same management, business smanager, and it was a suggestion from them, so we put it together.
"We've done so many collaborations in the past, so, for us, it just seemed something very natural. And I think for him as well, it was something new and very cool to experience."
Steve wrote about the collaboration in an online post. He said: "I had the biggest blast this weekend performing with SEPULTURA at Rock In Rio. The whole event was just magical and SEPULTURA was firing on all cylinders. Great group of guys and killer band."
SEPULTURA is currently headlining a North American tour with support from German thrashers DESTRUCTION and American melodic tech-deathsters ARSIS. The mayhem kicked off in Phoenix, Arizona on May 10 and will end on June 14 in Grand Junction, Colorado.
SEPULTURA's latest album, "The Mediator Between Head And Hands Must Be The Heart", sold around 1,800 copies in the United States in its first week of release. The CD came out on October 29, 2013 via Nuclear Blast Records.
