The California rapper and Missouri singer-songwriter have already broken records with the biggest co-headline tour in history, consisting of 39 shows across North America and Europe. It serves as one big celebration of their recent achievements - Lamar's hit album GNX and SZA's deluxe edition of SOS, which both came out in 2024.

Lamar has been riding high since releasing the scathing diss track earlier this year – sweeping up seven Grammys, headlining the Super Bowl, and dropping a critically acclaimed sixth album, GNX. The Grand National Tour, the rapper’s first all-stadium tour which kicked off in the US in April, is the latest iteration of this.
