3WW is the first single, and opening track, off of Alt-J’s third full length LP, Relaxer. The title ‘3WW’ stands for “3 worn words”. This song’s teaser uses imagery and scenery taken from the Japanese PlayStation 1 game known as “LSD: Dream Emulator”. In a newsletter to fans the band said that the song “traces the adventures of a wayward lad on England’s northeast coast, culminating in the whispering of three worn words. Let’s not beat around the bush – we think it could be the best thing we’ve done to date.”

The official music video for the song was directed by Young Replicant and was filmed in Real De Catorce, Mexico.

This song’s release was also themed after the number 3. The teaser for the song was released on 3/3, the full song was released 3 days later, and the album was originally set to release 3 months and 3 days later. The song also features 3 singers (Joe Newman, Gus Unger-Hamilton and Ellie Rowsell) singing as 3 different characters. The “3” motif also fits the three sides of the band’s triangle symbol.
