In a new interview with “USA Today,” Vicky confirms that fans will get to hear unreleased songs by Chris and Soundgarden sometime in the future, saying “everything will be release”... although there’s no telling when so far.
“All of Chris' music, including Soundgarden, will see the light of day because there's nothing in the world that lifts me [more] than sharing Chris' gifts, having people speak his name, and having his music out there,” Vicky says. “He’s alive that way and his legacy lives on, so everything will be released.”
