They've become a YouTube sensation by taking modern songs and giving them a vintage twist, and on Friday night US group Postmodern Jukebox performed to a sold-out crowd in Wellington.
It's the sound of the mid 1900s that's currently flavour of the month on YouTube.
Postmodern Jukebox has found the formula to get the massive online clicks - taking modern pop songs and giving them a lashing of nostalgia.
The band's story is as unique as its members - bassist Adam Kubota was at law school in New York when friend and PMJ mastermind Scott Bradlee came calling.
"He would send me text messages being like, 'Hey I'm going to record these cover videos in my basement, I think it's a good idea, I can't pay you very much but I'll buy you lunch, and I think it's going to work out'," Kubota recalls.
And it certainly did.
PMJ have put their unique twist on dozens of pop songs - including one of our own, which has racked up over 15 million hits on YouTube.
Kubota praises what he calls the democracy of YouTube for making them successful, as it's cut out the music label doorkeepers.
"For Postmodern Jukebox we're like, 'Yeah we're going to do a 1920s version of Kesha's songs' or something like that and I think if you were to pitch that to a music exec they'd tell you to get off at the next floor."
PMJ's just come off a sold-out 75-show European tour. When they're done with New Zealand and Australia, life on the road will continue for the group as they finish up with a trip around the US.
