From the moment they got stuck in to the bass driven Fitzpleasure the crowd were with Alt-J as the band completed their Latitude journey with the Friday headline slot.
Despite having just two albums of material to work with the Leeds four-piece were able to fill the stage with their melting vocals and beautifully layered sound.
The set started out with a series of tracks from their Mercury Music Prize-winning debut album, An Awesome Wave, to the delight of the audience.
Although alt-J tend towards slower tracks the crowd were happy to dance to the broad drum beats.
While not a chatty band they thanked the crowd saying it was one of their favourite shows ever having made their way from the Lake Stage to the Obelisk Arena.
After a swift break for the encore now expected of headline acts the band returned to play a cover of Lovely Day, by Bill Withers before rattling through a few newer songs.
The concert came to its crescendo with the anthemic Breezeblocks which had everyone in full voice.
alt-J certainly proved they could headline such a large festival and it will be interesting to see where they go from here.
