After weeks of pre-release cryptic tidbits surrounding the forthcoming and much-anticipated new album "Reflektor" from Montreal-based indie rockers Arcade Fire, the band’s titular first single appears to have leaked online.

Scheduled to be released on Monday, Sept. 9 at 9 p.m. as part of the band’s “9/9/9” marketing campaign, the James Murphy-produced dance number has been delighting fans of the band this weekend, after Pitchfork posted a Bandcamp stream of the tune, according to Stereogum. The file has since been made invalid.

The song, which features a distinct retro disco sound with electronic flourishes, is filled out by a melancholic voice that sounds a lot like David Bowie. The British artist has been rumoured to make a guest appearance on the band’s fourth album.

According to the British newspaper The Sun, the pop icon recently joined the band for a recording session at New York’s Electric Lady Studios, where they recorded a track for the album.

For weeks, Montreal’s most-famous music export has been slowly releasing morsels of information related to its new album, set for release on Oct. 29. But fans have been anticipating another date: Sept 9. That date is a part of the band’s clever “9/9/9” underground marketing campaign.

Along with a secret Instagram account, a new website, a cryptic teaser video, and street art that popped up around the globe, the campaign has been holding fans’ attention.

The veil of secrecy surrounding the campaign, however, was lifted last week when filmmaker Anton Corbijn told the Daily Beast about his latest project.

"I’m working on a really great song at the moment: Arade Fire’s new single," Corbijn, the man behind Nirvana’s "Heart-Shaped Box," said in the interview.

"The song is called Reflektor, and you’ll be able to see it Monday …. I can’t say much more than that, because it’s all a surprise. You’ll have to watch the TV Monday evening."

Arcade Fire’s previous studio album, 2010’s The Suburbs, topped charts in Canada and around the world, and won them numerous accolades, including a Grammy Award for Album of the Year.
