Following a bombastic performance at Sunday night's KROQ Almost Acoustic Christmas show at Los Angeles' Shrine, enigmatic Arcade Fire leader Win Butler found himself in a deep, dark basement -- the Hollywood speakeasy Dirty Laundry, where he DJ'd an afterparty for a smattering of lucky invitees and industry attendees.

Taking over for -- and then collaborating with -- an in-house DJ, Butler blasted through unlikely pop hits ("Pump Up The Jams," anyone?) as well as Haitian-dance jams, which were abetted by live drumming from one of the band's touring percussionists, who brought a hand drum he shared with the ebullient, sweaty, small crowd.

Butler wasn't the only performer in attendance: Noel Scaggs from funk-rockers Fitz and the Tantrums took court in the venue's intimate back room, greeting well wishers and taking photos with them. Phoenix's Thomas Mars was spotted in the room with Lorde, whose performance at the concert was easily the most-anticipated of the night.

She crushed it at the show, and though the New Zealander is famously underage, having just turned 17, there was nothing salacious that we saw at the afterparty -- just Lorde in a corner with some equally young-looking friends clearly enjoying themselves.

The aftershow bash was still going strong at 2 a.m. -- past last call for Los Angeles, but clearly not for the lithe model-types who were still breaking it down, with buckets of Red Bull out to keep them shaking all night.
