Metallica's James Hetfield adds that the band still feel as though they are "progressing" by writing new songs.

Metallica’s Kirk Hammett has suggested Guns N’ Roses have become a “nostalgia act” with their recent reunion tour.

GN’R packed stadiums across North America on this summer’s Not In This Lifetime… Tour, but have not released an album since 2008’s ‘Chinese Democracy’. That album was in itself the band’s first in 15 years.

“Unfortunately, they’ve turned into somewhat of a nostalgia act, which to me is kind of sad,” Hammett told the LA Times.

Metallica, by contrast, are preparing to release ‘Hardwired… To Self-Destruct’, their first album since 2008.

“I don’t want to think we’re trying to stay young by writing new stuff, but it makes us feel relevant,” Hammett’s bandmate James Hetfield explained. “It makes us feel like we’re still progressing.”
