The dark forest path that is Reflektor‘s marketing strategy continued through another foggy bog last night when Arcade Fire hopped onstage at a salsa bar. The band was back home in Montreal, and had decided, for whatever reason, that Salsatheque was to be the venue of choice for a secret show of new material. As The Main reports, concert-goers would be thrown out with any move towards their phones or cameras.

The set was described as “unexpectedly dance-oriented, due to the upbeat rhythms of conga drums and electronic flourishes…they traded their somber orchestral sound for something more contemporary.”

Arcade Fire will release the album’s first single this Monday at 9 p.m. Check out the trailer for Reflektor below.
