Without much fanfare, Billie Joe Armstrong and Mike Dirnt of Green Day performed at a New Year's Eve party in L.A. with their all-covers side band The Coverups.
The occasional outfit, who'd also done a Bay Area show before Christmas, was joined by Guns n' Roses bassist Duff McKagan and Jesse Malin on a bunch of punk rock anthems, including The Damned's "Neat Neat Neat" and The Heartbreakers' "Chinese Rocks." Snippets of both are posted on Instagram.
They don't just play punk rock, though. They've also tackled classics by Led Zeppelin, David Bowie, Mott the Hoople and INXS at the recent shows.
