Canadian metal innovators VOIVOD were joined by their former bassist Jason Newsted and DOWN/ex-PANTERA frontman Philip Anselmo during their June 23 concert at Hellfest in Clisson, France to perform the songs "Voivod" and "Astronomy Domine" (PINK FLOYD cover), respectively. Professionally filmed video footage of the concert can be seen below.Newsted joined VOIVOD in 2002 and served as producer for the metal legends' self-titled album in 2003 on the Chophouse Records label (in association with Surfdog Records). Longtime friends and pioneers of metal music, Newsted and original VOIVOD vocalist Snake (a.k.a. Denis Belanger), guitarist Piggy (a.k.a. Denis D'Amour), and drummer Away (a.k.a. Michel Langevin) first began working together at Newsted's Chophouse studio in 1995, intent on keeping the music alive between busy touring schedules. However, with Newsted's departure from METALLICA in January 2001, he was free to join VOIVOD as a full-fledged member and would remain involved with the group until 2008.
