It’s safe to say ‘90s nostalgia is running in overdrive this week, what with Pulp’s celebrated return to the U.S. and Coachella sets from Refused, James, Mazzy Star, and Dr. Dre and Snoop Dogg.

But here’s a reunion almost nobody saw coming: The post-‘Live Through This’ lineup of Hole -- Courtney Love, guitarist Eric Erlandson, bassist Melissa Auf Der Maur and drummer Patty Schemel—briefly took the stage together last night (April 13) at the tiny club Public Assembly in New York.

The occasion was the official after-party for 'Hit So Hard,' a documentary about Schemel’s battles with drug addiction and rock stardom. Originally billed as “a performance by Patty, Melissa, and Eric of Hole,” the party turned into something legendary when Auf Der Maur called Love to the stage.

The reunion seemed to take everyone by surprise.  Author Mark Yarm, who penned the exhaustive and fascinating grunge tome ‘Everybody Loves Our Town: An Oral History of Grunge,’ first speculated on the reformation via Twitter last night: “At @hitsoharddoc after-party. Word is @Courtney is going to show. @Holemusic reunion?!” Several hours later, he confirmed his own suspicions: “Hole reunion! @Courtney Love onstage now.”

The quartet performed Hole’s signature single, ‘Miss World,’ and a cover of the Wipers’ ‘Over The Edge’ (which Pitchfork astutely pointed out the band covered on a 1992 tribute album). The songs marked the first time in over a decade this particular lineup had played together.

Love seemed to be in good spirits and made no mention of her tumultuous week, during which she went on one of her famed Twitter rants against daughter Frances Bean Cobain and ex-Nirvana drummer/current Foo Fighters frontman Dave Grohl.
