Ozzy Osbourne BandNewsted joined Canadian thrash metal band Voivod in 2002. Coincidentally, he was also Robert Trujillo's (Trujillo being Newsted's replacement in Metallica) replacement in Osbourne's band during Ozzfest 2003, which included Voivod as a Second Stage act. During an MTV interview, both Osbourne and Newsted showed extreme enthusiasm in writing a new album together, with Osbourne comparing Newsted to "a young Geezer Butler." However, this would not come to fruition as Newsted left Osbourne upon finishing tour duties in late 2003. He would soon be replaced by Rob Zombie bassist Rob "Blasko" Nicholson.
Newsted then focused solely on Voivod where, much like Echobrain, the group was funded entirely through him. They recorded two albums before Newsted's participation in Rock Star Supernova, a supergroup created through the reality television series, Rock Star: Supernova, in 2006.
Rock Star SupernovaSupernova formed the basis of the second season of the Rock Star television program on CBS in the quest to find a lead singer. The show began online on the Rock Star web site on MSN on Monday, July 3 with an Internet exclusive weekly episode and premiered on CBS on July 5, 2006. Votes were cast via the Rock Star website. On September 13, 2006, Lukas Rossi was crowned the winner.
InjuryOn October 23, 2006, Newsted was injured while attempting to catch a falling bass amp head. The accident resulted in a torn anterior labrum in his left shoulder and a rotator cuff and biceps tear in the right. He was scheduled for immediate surgery, and underwent a lengthy rehab process.
Newsted has been out of the public eye ever since.
