The Full 2023 Splendour in the Grass Lineup Is Here with Flume ...

Maybe your 21st birthday was the best night of your life. Or, perhaps you're still planning for the 21st to end all 21sts. Apologies to everyone in those two categories, plus everyone in general as well — because Splendour in the Grass' just-announced 21st-birthday lineup with Lizzo, Flume, Mumford & Sons, Lewis Capaldi and the Yeah Yeah Yeahs has all other 21st shindigs beat.

Lizzo was first unveiled as one of this year's Splendour headliners back in March, and now she has some good as hell company on the full — and huge — bill. When the fest returns to the North Byron Bay Parklands stage from Friday, July 21–Sunday, July 23, the US rapper, songwriter, singer and flautist will top the Friday night, with Flume doing the same on the Saturday and Mumford & Sons following on the Sunday.

Flume's set is an Australian exclusive, celebrating ten years since his self-titled album and coming after his recent Australian tour in late 2022. Mumford & Sons are also doing an Aussie-exclusive gig, after last heading our way in 2019.

Among their ample company, Lewis Capaldi will take to the stage on the Friday night, while the Yeah Yeah Yeahs will play Saturday — making the trip to Australia after initially headlining 2022's Splendour in the Grass lineup, but cancelling in the lead up.

Music lovers hitting Byron Bay can also look forward to Hilltop Hoods, Sam Fender, J Balvin, Slowthai, Little Simz, Idles and Tove Lo, plus Arlo Parks, Ball Park Music, 100 Gecs doing another Aussie exclusive, Pnau and King Gizzard & the Lizard Wizard — and more.
