Check out this footage of Canadian prog/thrash innovators Voivod performing with former bass player Jason “Jasonic” Newsted (ex-Metallica). Newsted is currently involved in his self-titled solo act Newsted who were also performing at the three-day open-air festival, but took the time to join his former band onstage for the song “Voivod,” from their first album War and Pain (1984).

Ex-Pantera vocalist Phil Anselmo, who was there with his band Down, also made an appearance, joining vocalist Denis “Snake” Belanger for the song ‘Astronomy Domine’. Like Newsted, Phil is also involved in a solo project, Philip H. Anselmo and the Illegals. Check out the footage of him performing below.
