Near the end of Paul McCartney’s massive 39-song set in Seattle, Nirvana bassist Krist Novoselic join McCartney and his band onstage to jam 'Helter Skelter.'
Both Krist Novoselic and Dave Grohl were part of one of the biggest bands ever in Nirvana, but in April 1994 Nirvana ended with the suicide of frontman Kurt Cobain. Both musicians recently spoke with Rolling Stone about their reflections on the groundbreaking band and still dealing with the aftermath nearly 20 years later.
