A poster for Since They Left Us, a possible documentary on the return of The Avalanches, has been printed with a phone number that, when dialed, plays a twenty second loop of music that also appears in the Since They Left Us trailer.
The hotline was revealed on Reddit when a user investigated a photo of the poster tweeted by journalist Matthew Horton in London's Hammersmith Road. The number is billed as a line for "preview screenings" of the Since They Left Us trailer, but only plays music. Some claim that if you Shazam the track, the title is listed as "Subways," but when we did it both the artist and title were listed as "Unknown."
A representative for The Avalanches was not immediately available for comment. Watch the trailer for Since They Left Us below.
Update, May 25 (11:49 A.M.): A representative for The Avalanches has emailed The FADER a U.S. version of the hotline: (855) 953-3597, or (855) WLD-FLWR.
