Tuesday night at Paladino's club in Tarzana, California, Foo Fighters played a "secret" show where the group debuted new songs from their upcoming album, due out next year. But fans were treated to an even bigger surprise during the Foos set: the surviving members of Nirvana — Grohl, bassist Krist Novoselic, and touring guitarist Pat Smear — reunited on-stage for the first time since 1997. (Singer Kurt Cobain committed suicide in 1994.) Fittingly, the group performed Grohl's sole Nirvana composition "Marigold," which appeared as a b-side on the 1993 single for "Heart Shaped Box," according to a report on Blabbermouth and confirmed to SPIN by the band's rep.
