We were all left in suspense when Splendour in the Grass announced a "Mystery Oz Act" when they dropped their lineup last month. Well, the wait is finally over. Splendour have announced the mystery act will be none other than psychedelic surf-rock legends OCEAN ALLEY.

The six-piece will be joining the likes of Chance the Rapper, Tame Impala, Childish Gambino and Foals at North Byron Parklands this July.

With two albums under their belt, Lost Tropics (2016) and the critically acclaimed Chiaroscuro (2018) the band has continued to captivate audiences worldwide, clocking up a massive 96 shows across 10 countries, as well as selling out 15 Australian shows, in the last year!

Splendour returns Friday 19 till Sunday 21 July at North Byron Parklands, Tweed Valley Way, Wooyung.

Check out the full lineup below.
